Next week my professor will give me a bunch of thesis in domain of Condensed matter physics and I have to pick one of them, my main goal is to pick the one that guarantees me a good paycheck, I've been working minimum wage job to support myself since age of 17 that's why I just want money.

How to know which ones are the best to pick because he told me that he will suggest some which are more into theory and other more into applications..?

I think you know how this shit is decisive for my future
