The same happening can happen to 2 different individuals: good or bad or neutral, but how they deal with it will lead to different outcomes. What you think has everything to do with how you are going to react to any event. The better you think, the more likely you will enjoy the outcome. It goes deeper than that... Thoughts are vibration and energy. They are powerful. A single great idea or call it "inspiration" can get somebody motivated enough to start a project and keep at it for years and make a fortune with it.
