Twenty to twenty-five. These are the years! Don’t be content with things as they are… Don’t take ‘no’ for an answer. Never submit to failure. Don’t be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes, but as long as long as you are generous and true, and also fierce, you cannot hurt the world or even seriously distress her. She is made to be wooed and won by youth.
– Winston Churchill
