Gratitude will unlock all other virtues and is something you can get better at
Your 20s are the perfect time to do a few things that are unusual， weird， bold， risky， unexplainable， crazy， unprofitable， and look nothing like "success". For the rest of your life， these experiences will serve as your muse
Every breakthrough is at first laughable and ridiculous. In fact if it did not start out laughable and ridiculous， it is not a breakthrough.
For a great payoff be especially curious about the things you are not interested in.
Your time and space are limited. Remove， give away， throw out things in your life that don‘t spark joy any longer in order to make room for those that do.
If you repeated what you did today 365 more times will you be where you want to be next year？
You are as big as the things that make you angry.
When someone tells you about the peak year of human history， the period of time when things were good before things went downhill， it will always be the years of when they were 10 years sold — which is the peak of any human’s existence.
Don‘t bother fighting the old； just build the new.
At a restaurant do you order what you know is great， or do you try something new？ Do you make what you know will sell or try something new？ Do you keep dating new folks or try to commit to someone you already met？ The optimal balance for exploring new things vs exploiting them once found is: 1/3. Spend 1/3 of your time on exploring and 2/3 time on deepening. It is harder to devote time to exploring as you age because it seems unproductive， but aim for 1/3.
To signal an emergency， use the rule of three； 3 shouts， 3 horn blasts， or 3 whistles.
You can be whatever you want， so be the person who ends meetings early.
We tend to overestimate what we can do in a day， and underestimate what we can achieve in a decade. Miraculous things can be accomplished if you give it ten years. A long game will compound small gains to overcome even big mistakes.
Make stuff that is good for people to have.
