If you want to improve your memory try writing down all your worries. Researchers have speculated that the cathartic act of writing down your feelings may free up cognitive resources in your brain.

An optimistic image of the future not only shows us how to get there, but it draws us to it, drawing us towards our dreams (outside the comfort zone), like a magnet.

When you realize your expectations are selfish, then you'll know whom to blame your disappointments on.
