I was reading a book and i found this to be very interesting, and loked to share it with you.

"Suppose that we place on the ground a plank 30 feet long by 1 foot wide. It is evident that everybody will be capable of going from one end to the other of this plank without stepping over the edge. But now change the conditions of the experiment, and imagine this plank placed at the height of the towers of a cathedral. Who then will be capable of advancing even a few feet along this narrow path?"

"Simply because in the first case you imagine that it is easy to go to the end of this plank, while in the second case you imagine that you cannot do so."

"Notice that your will is powerless to make you advance; if you imagine that you cannot, it is absolutely impossible for you to do so"

This right here plays a big part in our seduction ans social skill game, most of us doubt ourselves and so we imagine the worst scenarios and that's why most fail due to this
