Do you usually do the opposite of what you are supposed to do?

Sell low and buy high, rather than buy low and sell high?

It seems to me to be a very tempting inclination that most people seem to have (especially if they are not really trained in trading), and it seems that it is possible (but difficult) to train yourself out of thinking and feeling like that in order that you are prepared to do the right thing when the rubber hits the road (that is to buy low and to sell high).
