Truth is fundamental. The reason the world today is what it is is because so much of it is based on lies... On deceit. Happiness based on lies is like walking on ice: You can ignore the fact that bellow you there is a river, but there's only so much it can take, and sooner or later, it breaks, and while you were busy jumping on the ice, you never learned to swim...So you'll drown.
What I'm saying is, all lies shatter, sooner or latter... Happiness isn't true unless it's based on truth, in honesty... Cause that's the one that lasts. When you finally accept things for what they are, and begin enjoying them for it, that's when you're truly happy...
It's like the old "if I can't see it, it's not there" thing. If you're standing in front of a lion and the lion's hungry, you can close your eyes and pretend it's not there... But it is...And it's still hungry... Sure you can fool yourself into being happy while it doesn't eat you, but sooner or later it will... The only way to really be free of it, is to deal with it.
Lies are a jail of happiness.
