It is the source of all true art and science. The secret to creativity is knowing how to hide your sources. When you sit with a nice girl for two hours you think it's only a minute. But when you sit on a hot stove for a minute you think it's two hours. Whoso neglects learning in his youth loses the past and is dead for the future.
