Why must there be uncertainty? Not just for one's self, but everywhere.

Some might argue that uncertainty keeps the world from plunging into chaos, but I argue that it keeps us from the things we need and want from life. If someone has impressive credentials all around, should it matter that their personality isn't what you consider to be perfect?

Uncertainty and self-doubt are tools of the devil. Life could and may be lived to the fullest and we'd know that if we didn't second-guess everything that shows up in front of us.

What kind of universe puts so many wonderful things in front of us, but also the sensibility to keep us from ever getting those things?
