Well ok, the OP didn't have to dip into her pocket for her tuition. Got it
Regardless, even if her Ph.D is free, she spent a lot of time achieving it, and once graduated, if a math degree pays kakaa, then I am still correct, that the ROI is not there.
Anyone that can achieve an Ph.D in math has the brains to do so much more to make $$, because to be happy in this life, one needs options, and options cost money...I know, I wrote this too many times, but it is really that simple....you wanna be happy? Provide yourself options...they are not free!!
HomeWork, yes most developers make sub $100,000 per annum....because most are not very good businessmen....they have the brains but not the wisdom....they are mostly lemmings that work for someone else, making someone else reeech....I work for myself and make myself reeech.
People don't so much lack knowledge, as they do wisdom...no college in the world teaches wisdom....
