Who said it?

The quote was simply this:

1) "Adversity reveals genius while prosperity conceals it."

Who said it? And was he Greek or Roman?

And while we are playing "Who said it" games, how about this one:

2) "Respect your efforts, respect yourself. Self-respect leads to self-discipline; When you have both firmly under your belt, that's real power."

or this one:

3) "They must often change who would be constant in happiness and wisdom."

or:

4) "One has to question the wisdom of trying to improve what we don't understand."

and, lastly:

5) "I am what I do."

Here are the answers. Mixed to provide yet another challenge to your fine and wonderful self:
