Perspective
At this point of life, I fully realized that no failure is actually a failure. When I have put my best effort and tried my best, yet it still didn't work as how I predicted, most of the times, it was how life tells me, “it is not your way”.
Most people find it hard to describe what they want, but I believe everyone knows what he/she doesn't want. It actually works the same. To pursue what we want or to avoid what we don't want, both will take us to the similar point.
It's just a matter of perspective. Life is.
