If at all possible, have kids. Children are extraordinary and infuriating, and among the most powerful human experiences available to us. Kids are a front row seat to the most extraordinary of spectacles: the unfurling of a human life. Mommy and I are so lucky to have you boys … we are grateful every day. Having your own kids is also a good way to rediscover humility when you think you’ve figured it all out. And humility opens us up to powerful new experiences and relationships. Don’t have them too soon, or too late, and don’t underestimate the challenge, but for gosh sake have em, if you can.
Community, broadly defined to include all relationships with other people, is everything. It’s not 60% of happiness, it’s 99%. Everything you think is important — success, building things, writing novels, gaining status — is important only insofar as it nourishes your current and future possible relationships.
If you drink green tea without sugar 30 times, it will taste acrid and mouth-puckering the first 29 times, and on the 30th it will taste pretty good. This is true of everything … there is no activity or habit you can’t develop a taste for. So you may as well develop a taste for things (and people) that are good for you.
