25 Principles of Adult Behavior

Be patient, No matter what. Don’t badmouth: Assign responsibility, never blame. Say nothing behind another’s back you’d be unwilling to say, in exactly the same tone and language, to his face. Never assume the motives of others are, to them, less noble than yours are to you. Expand your sense of the possible. Don’t trouble yourself with matters you truly cannot change. Expect no more of anyone than you yourself can deliver. Tolerate ambiguity. Laugh at yourself frequently. Concern yourself with what is right rather than who is right. Never forget that, no matter how certain, you might be wrong. Give up blood sports. Remember that your life belongs to others as well. Do not endanger it frivolously. And never endanger the life of another. Never lie to anyone for any reason. (Lies of omission are sometimes exempt.) Learn the needs of those around you and respect them. Avoid the pursuit of happiness. Seek to define your mission and pursue that. Reduce your use of the first personal pronoun. Praise at least as often as you disparage. Never let your errors pass without admission. Become less suspicious of joy. Understand humility. Forgive. Foster dignity. Live memorably. Love yourself. Endure.

When I look back over the last 25 years, in some ways what seems most precious is not what we have made but how we have made it and what we have learned as a consequence of that. I always think that there are two products at the end of a programme; there is the physical product or the service, the thing that you have managed to make, and then there is all that you have learned. The power of what you have learned enables you to do the next thing and it enables you to do the next thing better. — Jony Ive
