Not because you have to, but because you WANT to! Things you enjoy, even when no one around you wants to go out and play. What lowers your stress/blood pressure/anxiety level? Make a list, post it to your journal... and then tag 5 friends and ask them to post it to theirs.
And in no particular order:
-Petting a cat
-Hanging out with friends
-Reading a good book
Lessee...I'll tag...roisnoir, meepeek, eslin, kotikokura, and whoever else wants to give this one a try.
