Everyone has limitations. Refusing to accept them can cause all kinds of long term harm. (This would be me.)

Keeping a positive attitude and knowing where you are and where you want to be is important but lying to yourself is a long, slow descent into self-destruction.

It's not a lie, if you believe it. (I'm talking about statements about one's self only).

I'm not talking about saying "I can fly" and jumping out the window. It's within the limits and confounds of what is possible from one's own perspective.
