Critical review. Please don't be offended.
the task
What task? Only one? Does this mean you believed you could do everything else in the world but not this one "task", and that self confidence got you through it? This statement makes you sound silly. You need to get specific. Your whole paragraph is general. Illustrate how self-confidence got you past a hurdle and why it did, more importantly illustrate why your self confidence is scholarship worthy.
Besides, identifying my weaknesses and strengths enable me to improve myself to a better one.
"Besides" is too candor... and a better what?
Self improvement is not about changing the world... In fact you rush through tith self-help, friends' variety of personalities, all without elaborating on anything. This doesnt dhow organized thought.
In the end, you say that you believe your values help you face challenges... In your intro you solely identified self-confidence...
You need to make an outline of what you hope to write and convey.
