Don't we really like it when thing's seem to go a lot easier than we initially thought? A part of us seems to expect the worse, though isn't this kind of attitude a danger in itself? We end up setting ourselves up with the wrong face on our shoulders and perhaps cause more tension then needs be.
Why not anticipate the unknown and say to yourself, I wonder how this may turn out. If thoughts of doubt linger over our head then they will affect our treatment towards a subject we may not feel 100% about. I think sometimes we don't give ourself enough credit in the power we have individually to change something around. In a way, what only makes something a little bit uncertain are the vibes we create with our mind. Our attitudes and levels of confidence represent to others as much as ourselves our capabilities, something only exists in truth if we all agree and believe it too. We can't always assume the worst.
