It's perfectly okay to want to quit - as long as you don't.
If it's not fun, you are not doing it right.
It's a lonesome walk to the sidelines, especially when thousands of people are cheering your replacement.
Success, in my view, is the willingness to strive for something you really want
Ignoring facts does not make them go away.
Cultivate your desire for success to be greater than the fear of failure; Failure is merely a pitstop between where you stand and success. Failure allows you to learn the fastest; Failure inspires winners and defeats losers.
