I live for these kind of things..
I may work a lot,I may be sleep deprived and rarely go out,but I do take my gigs pretty seriously.
Here is why:
Play is serious business.
Taking some proper time every once in a while to do things that you really enjoy offers a lot of fulfillment.This will prepare you to face other responsibilities in life that may not be as fun but are still important to accomplish to create balance.
your body releases anti-stress hormones when you are havng fun,which enables you to relax, especially if you are taking part in activities that requires physical energy. You can strengthen not only your mind, but your body as well.
