Yeh, the nosy stuff will "kill ya", just don't. I think to often either we're looking at old history, or are going to put a negative spin on whatever we see. To often I have found it wasn't what I thought it was, so a lot of energy was wasted in worrying. Some things I would say are better left in the background, since they will dampen your drive and determination.

Focus on the positive and the work you have done on yourself.
