Has anyone turned there life with open MBA?

I'm 25, currently working as an SEO executive, earning way low than its required to survive these days. I am planning to do open MBA from DU this year or the next, I have completed my bachelor's 2 years ago and have been working in Digital Marketing ever since. Is it a good idea? My aim is to be Marketing consultant or something like that which pays well on an average, like 10-12 lakhs within next 3 4 years, is it possible? What should I do? I don't have any connections who can help me to get started with a good paying job, and not anyone who can guide me properly. Any help would be greatly appreciated.
