“Don’t try to be someone you’re not. Just be yourself.”
Of course, this is true insofar as it applies to hypocrisy, “white-washed tombs” and the like. But in another, very real way, this is cowardice. If you always sit comfortable exactly where you are, you will never make any progress. Don’t be satisfied with yourself. Strive to get better. Move from glory to glory.
If anyone wishes to grow, he must struggle and strive and fight to become someone he is not already.
