What's the best use of your time

Talking about the best use of your time, I think it is when you make the best use of your talent, energy and opportunities to show the best of you to the world.

  The best use of your time depends on who are you. In general, I can say:
1. Do some sport and take good care for your health.
2. Sleep well.
3. Do what you can do best (and what's good for you and for the others, or, at least not harmful for you and for the others).
4. Learn, study.
5. Make enough money via honest and legal means.

1) spending time with family or close friends
2) working on your dreams & goals

Best use time . Stop thinking and start doing.

[JamesNovak]

1) do something what makes you happy, whatever it is
2) eat
3) sleep
4) something where you learn something new
5) something what makes you fit
6) something where you have to use your creativity

Well said, except #1. Some things that makes you happy aren't healthy and/or safe at all.
