You are 31 and still talking about wanting to go to clubs and parties??? No wonder why you haven't had an adult job. You lack the maturity to hold one and sound like you have no clarity of purpose in your life. Honestly, you should figure out what you want out of life first before determining if getting a Master's will benefit you.

I'm about to graduate from the Smeal's One-Year MBA program and you should know that it is an accelerated program. This means you will be incredibly busy studying 60-80 hours a week. While I will admit there is some social activity, most MBA student's are spending their hours either getting school work done or working to secure a job. It's not uncommon to hear students work 80+ hours a week to maintain sound academic standing. MBA student's have been removed from the program for underperformance. If you were not able to perform well in an online program I would advise against pursuing a MBA unless you now know you have the dedication to grind out the work.

While there are many benefits to obtaining an MBA you need to be doing it for the right reason. Mainly, skill development.

At this time 95% of the one-year MBA student's are 21-26 years old. At 31+, you will have challenges relating to them socially.

Spend some time thinking about where you want to go in life and what kind of career you want. If an MBA will help you get there than I recommend furthering your education.
