If you have a success you have it for the wrong reasons. If you become popular it is always because of the worst aspects of your work.

Those who cannot work with their hearts achieve but a hollow, half-hearted success that breeds bitterness all around.

Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.

You might well remember that nothing can bring you success but yourself.

A rejection is nothing more than a necessary step in the pursuit of success.
