Of course, some intelligence must be applied here. No matter how positive you are, buying a Powerball lottery ticket still gives you a 1 in 292 million chance of winning. Those are not good odds! And there’s nothing your positivity will do.
The main thing positivity will bring you is the ability to take action. If you don’t think that doing something will work, you won’t do it. It’s that simple.
Remember, being positive doesn’t necessarily mean you’ll win, but being pessimistic definitely means you’ll lose.
