"Stop focusing on what you have to lose and start focusing on what you have to gain."

This quote is similar to the distinction between 'playing not to lose' and 'playing to win'.  When you play not to lose, your focus is on not making mistakes. Your execution will become really rigid.  You’re more likely to put pressure on yourself and not perform like you should.  On the other hand, when you play to win, you have nothing to lose and can attack the challenge head on.  This allows you to take chances on your way to earning the result, without fear of what might happen.

To continue, using a lens of positivity helps you see opportunity. The reality of every situation we inherit is we can either go up or go down. You can get promoted, or you can get fired. You can get engaged or break up. Although both possibilities seem equally likely, when you choose to focus on what there is to gain, the perspective you choose tends to be favored in your life and transpire more often than you would think.  So, use positivity to see all that there is to gain. Don’t focus on what you have to lose.
