A happy life consists not in the absence, but in the mastery of hardships.

Learning never exhausts the mind.

I'm doing many different things to prepare for the inevitable failure of one of them.

I learned that you have to push away the demand of people's expectations by believing in your instincts.

The truth is the light and light is the truth.

There will always be someone who can't see your worth. Don't let it be you.

It is not enough to know your craft — you have to have feeling.
