I'm 41, and just realized what the 3 important things are for a happy life.
1) Be healthy (eat healthy, exercise, sleep)
2) Surround yourself with family, friends and loved ones (lots of dinners, calls, conversation and games - create multiple 'homes')
3) Go for it (challenge yourself professionally, and personally -- strive for bold goals)
