No matter what, you will go into situations where you can win or lose. There is a level of preparation that is needed to get to the start line, sales call, or board room pitch. You need to make sure that you are ready to go, why not go with a winning mindset.
I think many people go into situations with a losing mindset and with that thinking you will certainly come up the loser, but if you go in with a winning mindset, you have a very likely chance to come out the victor! The interesting thing is, often that is the only factor between winning and losing, take what you have worked so hard to get and go home with the gold! - Ken
