I was reading this article, and had a sort of realization. It makes so much sense.
When you approach anything with an honest and deep belief that you can do it, and are not wavered by possibilities of failure; you really can achieve what you want. You might fail once or twice or even thrice, but if you find a way to keep your spirits high; you will succeed eventually.
We as human beings are naturally averse to risk and discomfort. We have to get out of our comfort zone, if we want to go to the next level.. Think of the last time you challenged yourself, how it turned out. You will find yourself growing as a person, when you take on challenges or do things that make you uncomfortable.
