From the movie The Producers, by Mel Brooks.

Bialystock: You think you’re not in prison now? Living in a grey little room. Going to a grey little job. Leading a grey little life.
Bloom: You’re right. You’re absolutely right. I’m a nothing. I spend my life counting other people’s money – people I’m smarter than, better than. Where’s my share? Where’s Leo Bloom’s share? I want, I want, I want, I want everything I’ve ever seen in the movies!
Bialystock: Leo, say you’ll join me.
Bloom: I’ll do it. By God, I’ll do it. I’m Leo Bloom. I’m me. I can do whatever I want.

You don’t have to be talking about breaking the law to talk about doing whatever you want. We all feel like we’re trapped sometimes in our lives. Prisoners to our routine. Making money for other people. Sweeping up a pile of money to be added to the coffers of old rich men. But this prison is safety. Trading comfort for satisfaction. It offers many freedoms, don’t get me wrong. But it also has many shackles that could be thrown off if it weren’t for the safety net offered by that grey little job, inside the grey little room. That’s why we voluntarily imprison ourselves. The shackles are light. But they’re still shackles.
