Live life, explore new things, be productive, love often, eat good food, feel good about yourself, stay interested.
I think of life as a wavy line (sine wave). There is always going to be ups and downs. Turn the 'down' parts of the line into productive periods, so that you can make the 'high' parts higher.
Example: Boss asks you if you want to work overtime this weekend. You don't really have anything going on, but you don't know if you want to spend your weekend working. But you go ahead and do it, and make alot of money. A few weeks later, you go to the Caribbean with the extra money you earned.
Or I guess you could spend all day on a forum, whatever floats your boat.
