actually, it is really a good choice to start a PHD study
and then become a professor in college
it is a good choice for MM!
since you have time to take care of your family, you earn much, your are respected, you have long vacation, and you don't have to worry about losing job
The future of a professor is good. But five years' PhD study and maybe five more years struggling for the tenure. There are ten years that you will have little personal life. If you don't like academic research, life will be so hard for you.
