GO FOR IT.
Can't nobody wrong you for going to school, it aint their life its yours so at the end of the day u have to look after yourself and build your own value.
Your plan sounds good it's not farfetch'd or impossible, and unlike 96% of people in society you actually HAVE a plan. Go for the cc - getting B's arent hard ESPECIALLY in a cc so As should be a breeze as well. Get in touch with someone from one of the colleges/universities and ask them about what requirements your gonna need to get there. As for an MBA those aren't hard to get either but in ur last 2 years of college/university you better have a good GPA (atleast a B), and from there your in a comfortable place & please dont listen to what good for nothing muthafuckas try to tell u about getting an MBA b/c real talk that shit ISN'T HARD - theres just a lot of lazy ass niggas who dont wanna work and want everything to be easy for them b/c their insecure.
As soon as you have that MBA to ur credentials ur pretty much set, dont listen to the niggas who go out of their way to say BAs or MBAs are useless them niggas is just stupid and feel inadequate about their talents in school, I can pretty much guarantee you that having the MBA >>>> not having one & seriously after what happened 2 years ago, along w/ financial reforms and etc. employers are gonna be looking for highly qualified people with a good understanding of what the work entails. & if thats not your aim to be hired and you wanna go the independent route then more power to you, I take it its prolly a lot easier for an MBA grad to get a loan from the bank or from people to start up their own company.
I wish you the best of luck in your pursuits.
