I don't have 10, but the following are my top things:
1. Academic success creates a framework of predictability, but newsworthy success requires social sophistication. The art of socializing ends up being far more important than academic achievement. After a decade of academic success through high school, college and grad school, then another decade of working in the trenches while observing the rise and fall of those around me, I realized the common theme between those that rise the farthest: well honed social skills.
2. Luck, serendipity or chance by far is the most elusive ingredient to success. Being the smartest, hardest working and most innovative mind is nothing if you are born a bush man trapped in the jungles of New Guinea. Given this insight, we must increase our opportunity for chance to take seed by "getting out", meeting people, doing things, traveling, etc. Sitting still is no different than locking the door and turning off the lights.
3. True unconditional friendships are harder to come by than a winning lottery ticket. So if you have one true friend, cherish and cultivate this relationship because you may not find another in this life time or the next. To be loved is a gift that must never be forgotten, because once lost, you may never find it again. Whether it's your spouse, workmate or tennis buddy, keep them always in mind.
4. If you can't afford college, don't sweat it. The gift for this generation, more than any other, is that work experience is worth more than a college education if you can get online.
5. In order to see yourself, do different things often and do many things differently. Sports, music, ballet, kung fu, MMA, dance, coding, drawing, massage, poetry, reading, listening, crying, movies. Do them with passion and discipline in addition to whatever your day job is. Live in the physical world, the creative world, the gastronomical world, the logical world. The more worlds you can traverse, the clearer your vision of self becomes. Spend a day in a classroom of preschoolers or juvenile delinquents, and listen. Volunteer in a retired group home and help residents work their smartphones. Many of my innovations arise from these experiences.
