Do you mind sharing some of your projects (even if its by PM)? In college right now and desiring a very similar lifestyle - trying to figure out how to translate my current PI niche into something more substantial.
I'm not sure why people ask what people's profitable projects are. Do you expect to just copy the idea? If so, why would they tell you? If not, what's the point of knowing what it is?
Seconded-- Any and all advice that can help lead to a low-cost, low-earning travel lifestyle would be much appreciated!
