I must throw in my 2 cents here-
An MBA is a tool. Just like a laptop or a screwdriver. It's a toolbox of skills and shrewdness, if you use it right.
It is what you make it. I was an elementary teacher 3 years ago, earning 34k a year. I decided to get my MBA. The exposure to new ideas, competitive minds, strategy, finance, marketing, and importance of tech aspects changed my life considerably. One year into it, I got a slew of tech certifications in my spare time and learned web design. 18 months in, I was teaching web design to adults and running a school's network. Now at $43k. 24 months in, I was running a website for 1/3 of a university and managing tech projects on the side. Hello, $52k. Grow, grow, grow. It's florida, where incomes are low, but I was happy oto be earning this just 2 years with my Bachelors in teaching.
Two months before graduation with the MBA, I went into business for myself. Built up a portfolio of clients and jumped. I no longer talk about my income, but I can tell you I am happy about everything except how much I'm now paying in taxes

The MBA taught me about competitive strategies. In addition to many websites, I do two to three phone consults a day, and more and more of them involve competitive strategy/marketing. Sure, I build networks and websites. But more than that, the MBA taught me to read people, situations, and make money for all parties in every situation.
RJ, I'm proud of you for earning the MBA. You will never regret it. The confidence, skill, wit, and shrewdness you gain is priceless.
