Reading Seneca: On the Shortness of Life

I started reading this expecting it to feel ancient. Like, this guy lived during the Roman Empire, what's he really gonna tell me about time that I haven't already heard repackaged in some productivity YouTube video?

But then he hits me with it early: life isn't short. We just waste most of it.

And I had to put the book down for a second because... yeah. That's true. That's actually really true and I didn't want it to be. We constantly hear from others that life is short, make the most of it and etc…

The thing nobody wants to admit

We do this thing where we treat time like it's everywhere but treat money like it's sacred. Someone asks for $20 and suddenly there's a whole negotiation. Someone asks for an hour of your time and you're like "yeah sure." And an hour becomes two and you look up and half your day is just... gone. To what? You're not even sure.

And here's the uncomfortable part, it's rarely one big thing that steals your time. It's a hundred small yeses you said without thinking. The meeting that didn't need you. The conversation you stayed in out of politeness. The tab you had open "just to check." None of those feel like a big deal in the moment, but they add up to weeks. Months. Seneca would probably say they add up to years.

So if you actually want to do something with this, start there. Not with a new app or a new system, in my case tons of notion productivity optimization — just start noticing. One day, track where your time actually goes. Not where you think it goes. Where it actually goes. You'll probably be surprised.

The preparation trap

Seneca calls out three specific ways people waste their lives and the one that got me was the preparation trap — spending all your time getting ready to do something instead of just doing it.

I've definitely been guilty of this and I’m sure alot of people who watches productivity system videos are too. Building systems, optimizing workflows, researching tools for a project I haven't actually started yet. Like the setup is the work. It's not. It's literally just procrastination with better branding.

And the sneaky thing about this trap is that it feels productive. You're not on your phone, you're not watching TV, you're "working." or atleast that’s how our brain interpretes it. But if you've been "getting ready" for six months and nothing exists yet, that's worth being honest about.

The fix isn't to stop preparing entirely. It's to put a limit on it. Give yourself a week to figure out the basics, then start. You will learn more from actually doing the thing for one month than from researching it for six. Every time. The imperfect version that exists beats the perfect version that doesn't.

Anxiety is just future-tripping

The other two ways Seneca says we waste time: living for other people's approval, and burning hours on anxiety or regret.

They’re different because they're not abstract. That's a random Tuesday where you spend three hours stressed about something you can't control. That's a Sunday night spiraling about a conversation you had Thursday that the other person probably forgot about by Friday.

He writes: "True happiness is to enjoy the present, without anxious dependence upon the future."

Which sounds simple until you realize how much of your mental energy right now is somewhere other than right now. Planning for a future that might not happen the way you're imagining. Replaying a past that you can't change anyway. Both of those are just noise, and the cost of that noise is presence.

If you want to actually use this: next time you catch yourself spiraling on something that hasn't happened yet, ask yourself — is there an action I can take about this right now? If yes, take it. If no, you're literally just choosing to suffer early. Drop it and come back when you can actually do something.

Who you spend time with matters more than people say

Seneca has this line about relationships that I keep coming back to: associate with people who are likely to improve you, and welcome those you can improve. Anything else is just comfort disguised as connection.

Is it a sorta cold take? Perhaps. But in my interpretation it's actually really generous when you think about it. It's not saying cut everyone off. It's saying be honest about what your relationships are actually doing. Are they pushing you somewhere? Are you bringing something real to them? Or are you just both kind of... there, out of habit?

Some of the most draining relationships aren't the obviously bad ones. They're the ones that are just flat. No growth in either direction. Just familiar. And familiar is easy to confuse with meaningful.

You don't have to blow anything up over this. But it's worth thinking about who you've been giving your best hours to, and whether those people even know that or appreciate it.

The "I'll do it later" lie

This is maybe the sharpest thing Seneca says, and he doesn't sugarcoat it: stop assuming you'll start living on purpose later. When things calm down. When you have more money. When the timing is better.

The timing is never better. That's not pessimism, it's just how it works. There will always be something in the way. The question is whether you're going to wait for the obstruction to clear or move anyway.

"The willing, destiny guides them. The unwilling, destiny drags them."

There really is no in-between. Either you're making deliberate choices about your life or life is just happening to you and you're reacting to it.

The practical version of this: pick one thing you've been "waiting for the right time" on. Not ten things — just one. And decide today, right now, what the smallest possible first step is. Not the whole plan. Just the first move. Then do it before you go to sleep tonight.

That's it. That's the whole thing. Seneca wrote two thousand years of philosophy that basically boils down to: stop waiting, start now, be intentional about what you give your time to.

What I'm actually taking from this reading

The thing I keep landing on isn't a new productivity framework. It's more like a lens shift. Moving from "I don't have enough time" to "what am I actually doing with the time I have?" Those sound similar but they're really different questions. The first one makes you a victim of time. The second one makes you responsible for it.

Life is long enough. We humans have some of the longest lifespans of any creature on this planet. Billions of people before us never made it past 40. Some people today still don't. We have more time than almost any generation in history, more tools, more access, more opportunity, and we still walk around complaining that there aren't enough hours in the day because death is a conversation nobody wants to have. We know it's coming and instead of letting that light a fire under us, we just... don't think about it. We push it to the back of the mind and keep scrolling. But that avoidance is exactly what Seneca is poking at in my opinion. The awareness of death isn't supposed to paralyze you, it's supposed to make the time you have feel real. You have to make the most of your time and cherish those you love, make memorable experiences.

The urgency isn't about rushing or cramming more in. It's about being deliberate. Showing up fully for the things you actually care about instead of sleepwalking through a life that mostly just happened to you.

You have enough time. You just have to actually use it.
