There should be at least one thing in your life you enjoy despite being no good at it. This is your play time, which will keep you young. Never apologize for it.

• You’ll never meet a very successful pessimistic person. If you want to be remarkable, get better at being optimistic.

• It is impossible to be curious and furious at the same time, so avoid furious.

• Working differently is usually more productive than working harder.

Asking “what-if?” about your past is a waste of time; asking “what-if?” about your future is tremendously productive.

Whenever you hug someone, be the last to let go.

Never hesitate to invest in yourself—to pay for a class, a course, a new skill. These modest expenditures pay outsized dividends.

Don’t work for a company you would not invest money in, because when you are working you are investing the most valuable thing you have: your time.

• Admitting that “I don’t know” at least once a day will make you a better person.
