Be confident, not certain - Eleanor Roosevelt

Never mistake knowledge for wisdom. One helps you make a living; the other helps you make a life.

The encouraging thing is that every time you meet a situation, though you may think at the time it is an impossibility and you go through the tortures of the damned, once you have met it and lived through it you find that forever after you are freer than you ever were before. . . . You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, “I lived through this horror. I can take the next thing that comes along.

Also, the importance that most Americans attach to the posts they hold, whether elective or appointive, is probably justified; for in prestige most public servants find their only return. Certainly the financial returns are slight in comparison to what the majority of them could earn in business or in a profession.
