Cogito ergo sum

"Thinking positively is the key to getting whatever you want."

I tend to forget that quite often and have to remind myself again and again.  Why is that such a hard concept for us to grasp?  Are we inherently pessimistic?  DId society make us this way? Our Parents? God?

It seems odd that the most advanced beings on this planet have to conciously remind ourselves to go out there and live life.

Cogito ergo sum.

(I think therefore, I am.)
