Inspire yourself never to waste time on bullshit again.
Having kids showed me how to convert a continuous quantity, time, into discrete quantities. You only get 52 weekends with your 2 year old. If Christmas-as-magic lasts from say ages 3 to 10, you only get to watch your child experience it 8 times. And while it’s impossible to say what is a lot or a little of a continuous quantity like time, 8 is not a lot of something. If you had a handful of 8 peanuts, or a shelf of 8 books to choose from, the quantity would definitely seem limited, no matter what your lifespan was.Paul Graham
Ok, so life actually is short. Does it make any difference to know that?
It has for me. It means arguments of the form “Life is too short for x” have great force. It’s not just a figure of speech to say that life is too short for something. It’s not just a synonym for annoying. If you find yourself thinking that life is too short for something, you should try to eliminate it if you can.
When I ask myself what I’ve found life is too short for, the word that pops into my head is “bullshit.” I realize that answer is somewhat tautological. It’s almost the definition of bullshit that it’s the stuff that life is too short for. And yet bullshit does have a distinctive character. There’s something fake about it. It’s the junk food of experience. 
If you ask yourself what you spend your time on that’s bullshit, you probably already know the answer. Unnecessary meetings, pointless disputes, bureaucracy, posturing, dealing with other people’s mistakes, traffic jams, addictive but unrewarding pastimes.
I’ve found that unless I’m vigilant, the amount of bullshit in my life only ever increases. Rereading Life is Short every so often gives me a kick in the pants to figure out what really matters and how to get the bullshit levels back down.
