If you want to learn something physical learn to play

If you want to learn something physical that is difficult; practice often and quit hungry for the experience. Practice for brief periods of time. Do not practice when you are tired and when you begin to make mistakes quit your practice. Imagine a golden thread fastened to the center of your chest pulling you to your next session “tomorrow at 8 AM–10 AM–whenever, I get to practice again. You want to look forward to your next session with a happy, expectant anticipation–not drudgery. It will keep your learning fun, interesting, and exciting.

Learn to play.

Make being healthy one of your hobbies

It certainly will be something that serves you well throughout your life. Make it fun. Study and learn as much as you can about what modern science and research says contributes to living a long healthy life. Devise a plan that is yours; then follow it. Get excited about living a vibrant healthy life; it is a worthy goal. Being healthy contributes (statistically) to living a long life. From about the time I was in my teens I have thought of old age as being 30 years older than I am at the time. Smile. I still feel that way today; I will be 72 my next birthday.
