It depends on what you are looking for and willing to put up with. Everyone is different in that regard. If you have the patience to be an instructor or fly for peanuts as an FO at a no-name regional for 10 years, then go for it.

If not, then get into flying as a hobby, get your ratings slowly, while using that MBA to pursue a career that actually makes money, and then switch into flying when opportunities open up.

I LOVE flying, and I LOVE teaching. However, it is not my primary career because I have a family to feed. There isn't a week that goes by where I'm not kicking myself in the a$$ for dropping out of college to pursue a flying career back in the day.
