Do I follow my passion or do I look for opportunities that bring lots of money?

I don’t think this is a mutually exclusive thing.

I don’t think you are forced to choose only one option and pursue it at the expense of another option.

I think you can do both. You can follow your passion and find a way to make money out of it.

Don’t choose one, choose both, why not?

Why don’t you compromise and be a millionaire artist or something? 🙂
