It's the Truth!
There are plenty of times I just want to give up... just cash it all in, give my stuff away, and just fade away from the world. And I doubt not too many would even miss me, maybe for a few months, then they would get over it. BUT, I always fight on. ;-)
I'm not sure if it's just my stubbornness or a hope that my life will get better, but either way, I keep breathing. Something in the universe won't let me give up, so I have no choice but to keep trying. :-)
