I want to do something that matters.
I just wanted to do something important.
There is only one thing I will not concede: that it might be meaningless to strive in a good cause.
Hard work is a prison sentence only if it does not have meaning.
The important point is to not just follow your passion but something larger than yourself.
A valiant man Ought not to undergo, or tempt a danger, But worthily, and by selected ways, He undertakes with reason, not by chance. His valor is the salt t' his other virtues, They're all unseason'd without it.
It is by translating your fine sense of aspiration into actual lofty deeds that you grow toward your ideal. Link your lofty thoughts to earnest, active effort, and good results will inevitably follow. The great things you intend to do some time must have a beginning if they are ever to be done, so begin something worthwhile today.
