Preparation is if not the key to genius, then at least the key to sounding like a genius.
Preparation is the most important part of the process. With an hour to solve a problem, one ought to spend 55 minutes thinking about the problem and 5 minutes thinking about solutions.

Preparation is not always what it appears. At times, when one draws back, it is sometimes only in order to have enough room for his leap.
Preparation is overdone. Beginning becomes an impossibility when we wait for the moment when everything, absolutely everything is ready before starting.
Preparation is the setting up of the table for the moment of action. If the fuel is prepared, it is hard to tell from where the spark comes that sets it on fire.
Preparation is a domain whose importance is rarely grasped. Most men spend the first half of their lives making the second half miserable.
