What happens when some wrinkle comes up in our life? Maybe your high-school/college superstar badge is not as shiny as it once was and your future goals of playing PRO are gone. You probably got disappointed, confused, angry, depressed. "How is this possible!?" There are many reasons to why things don't go your way in life. Some are your fault and you just have to realize it, laugh at it, and get better. Others are just things you can't control. Either way, you have an option to quit or take your failure as a fuel to get better.
If you are the tiny mouse character, you would take that as a bad day and you would be sniffing and looking out for new "cheese" the next day or get paralyzed and expect miracle to happen (human character).
