Personal revelation unveils your true capability and transforms your life for the better. Very few experienced this early in their lives and reaped its benefits that compounded overtime; a few experienced this late in their lives and had no enough time to finally put a dent in the world; most never experience this at all and continue to complain how meaningless lives are.
The only way to discover your revelation is to force yourself to do what you never thought possible, and complete it gracefully. When you realize it is not at all impossible, you subconsciously crave for more. You will want to challenge yourself to regain that high level of self-satisfaction.
Finish one impossible, and you will soon finish more impossible.
