Self-Confidence

To know that you have the potential to do something, with added effort, is the same as having the ability to do it. This is the concept of self-confidence.

The human mind can be so easily tricked by a lie to oneself, that it boosts it's own capabilities simply to match one's very wishes. The trick is to simply be calm, take one step at a time, and accept any outcome of an endeavor, though preferably a positive one. This has more to do with how our brains simply refuse to function properly in a state of chaos.

Disappointment leads to a lack of confidence. Lack of confidence leads to negative feelings. Negative feelings lead to chaos. Chaos leads to confusion. Confusion leads to mind block. Mind block leads to negative results.
It all boils down to this chain reaction. Need not be said, it is better to cut the chain off earlier.

Even winners lose sometimes. Nobody ever reigns as champion forever. In fact, champions themselves have tried and failed countless times before reaching where they are. They all share a certain trait: Resilience. The ability to come back exponentially better after a failure. While others crawl into their beds with negativity, they are the ones who knew that they needed to push harder in order to overcome the challenges they have faced. And even at the top, they often fail. But at that point, failure does nothing but amuse them.

To have resilience is to be confident even in the face of failure. It is to know that your ability is better than your recorded grade. It is to commit effort into trying once again.
