Mmmm...by being "Little"! :D
Stop being a bormal grownup and start living life as a kid again! I recommend coloring with crayons
! And LOTS of Legos! And footie pajamas
! And stickers
! 'n glow sticks
Generally speaking just surround yourself with positive, fun stuffs and start cutting out all the bad, negative stuff in your life. Most important...STOP WORRYING! Politics, religion, pfffft, "Littles" worry not about such inconsequential things. We're more concerned with where the red crayon went or where that Lego piece we just saw five minutes ago ran off to.
Stress is the big one, stress makes you old, makes you tired, makes you hate life and living. So get rid of it! Put on yer footie pajamas, pop a binkie in yer mouth and color with crayons for a few hours! Trust me, you'll feel a *LOT* better afterwards! ^__^
Oh and don't worry about what others think...every single last one of ~them~ will all be dead in less than a 100 years and in the grand scheme of history no one is ever going to remember any of ~them~ for anything, least of all whatever small minded, backwards, ignorant, NONpinions they had about you and your life. *nods*
