To rejoice at a success is not the same as taking credit for it. Only he who attempts the ridiculous can achieve the impossible. A book succeeds when its margins are full. The ultimate goal of the writer is silence. If you cannot win, make the one ahead of you break the record.
Failure is the true test of greatness.
When you insist you're not the kind of person who can climb a mountain or make a speech, all you are saying is that up to now you haven't done it. Those who think that they have arrived, have lost their way. Those who think they have reached their goal, have missed it. Those who think they are saints, are demons. It's great to be great, but it's greater to be human.
