1) You get 4,000 weeks if you're lucky

The average human lifespan is absurdly, terrifyingly, short. You get about 150 weeks in high school, 150 weeks in college, 500 Saturdays a decade. See Paul Graham's related essay screenshot below providing a quantitative sense of how life is not only short, but the finite time periods within it are even shorter. Once you accept that you can focus on what’s possible instead of trying to do everything. 

2) Civilization is relatively recent

60 100-year-olds back to back is all of civilization. That's fewer people than you've probably seen at a single birthday party. For perspective, you are:

• 35 people removed from the pharaos and pyramids
• 20 people removed from Jesus
• 7 people removed from the Renaissance
• 5 people removed from King Henry VIII
• 2.5 people removed from the founding fathers

("We have a bias to judge history from the short perch we occupy. Our few thousand weeks feel like the hinge of the universe - they aren't")

3) Accept you can't do everything

You will always have more to do then time to do it. And the faster you move the more things are given to you to move fast on ('the faster you answer email the more email you will get').

The day will never arrive when you have everything under control, when no one is angry with you for missing a deadline or dropping the ball. Controlling your life fully and meeting everyone’s demands and your own goals is not possible.

4) Tough choices are needed

Since we don’t have time for everything, we have to make tough choices between things. Every real-world way to live entails the loss of countless other ways of living. Practice strategic underachievement - decide in advance what to fail, what you’ll let slide to protect what matters. Identify the areas of your life that you won’t expect to excel in for some period of time - you can rebalance later (to a degree) to take a stand on what matters most to you.

5) Claim time

“After years of trying and failing to make time for her illustration work, by taming her to-do list and shuffling her schedule, Abel saw that her only viable option was to claim time instead—to just start drawing, for an hour or two, every day, and to accept the consequences, even if those included neglecting other activities she sincerely valued.” (see video metaphor - prioritize your foundational 'rocks' first)

6) Use the little moments of spare time

“The art of living is to make use of the spare time, the odd moments, that most men throw away.” (30 mins daily = 182 hours a year; the spare moments meaningfully add up)

7) De-instrumentalize time

Before the Industrial Revolution, time used to be the medium in which life unfolded, the stuff life was made of. After, once time and life had been separated it became a resource or input to be used.

Don’t be someone who is always living in the future, never enjoying the present but just looking at time as an instrument to help you get to the next point. Treat moments as ends in themselves, not just means. Rest and leisure have intrinsic value (sabbath, walks, looking around). You don’t have to be doing something for some other reason. Resting doesn’t have to be used for something else. In fact it’s the way to fully inhabit the world. 

8) Time isn't something we can ever really possess or fully control

You can have an expectation for how the evening or week or month or next chapter of your life will go, but you will almost always end up surprised.

Demand for reassurance from the future will never happen. The struggle for certainty is an intrinsically infeasible thing to get. Time just isn’t the sort of thing you get to order around like that.

9) There will be final occasions for everything

There will be a last time when you visit your childhood home, see an old friend, swim in the ocean, hug your partner, drop off your kid at school, etc. You never know in most cases when the last time will be.

Indeed there’s a sense in which every moment of life is a last time - it arrives, you’ll never get it again, and once it’s passed your remaining number of moments will be one smaller than before.

10) Your attention defines your life

What you pay attention to defines for you what reality is. It’s not just a resource. It is your life. Life is a succession of transient experiences valuable in themselves which you’ll miss if you’re completely focused on the destination to which they’ll be leading.
