Chase your passion, not your pension.

You have to be burning with an idea, or a problem, or a wrong that you want to right. If you're not passionate enough from the start, you'll never stick it out.

Do not hire a man who does your work for money but him who does it for love of it.

And, more importantly, reach for the stars. And realize that it is never too late—not now, not ever—for you to pursue you passion, your pursuit of perfection. And most importantly, your perseverance for making it happen.

An irresistible passion that would induce me to believe in innate ideas and the truth of prophecy has decided my career. I have always loved liberty with the enthusiasm which actuates the religious man with the passion of a lover and with the conviction of a geometrician.

Pleasure without joy is as hollow as passion without tenderness.

To play a wrong note is insignificant. To play without passion is inexcusable.
