Advice for a 29 y/o looking to break into "high" finance

What up guys!

I was looking to see if I could get some advice regarding what the next best course of action for me is with respect to breaking into "high" finance. I've been in banking for 6 years now but its only been working at a small credit union as a teller, personal banker, and now junior credit analyst. I recently got my BS in Economics and Finance from a non-target university and I have absolutely no internships or extra curriculars and I have limited knowledge and competency in firm valuation, Security Analysis, and excel.

Initially I was very much interested in breaking into IB but after doing research around here and talking to a couple of people in the business I've come to the conclusion that IB may not be the best fit for me at this point in my life. IB analysts hours are very demanding and given that I'm 29 and would like to start a family in the not too distant future, I'm not sure working 80-100+ hours a week is conducive to those efforts. IB is probably out of the question at this point, but I was also interested in ER, S&T, and CF. Are the hours in those industries similar to IB?

Given my brief background and my other interests within "high" finance, what steps should I be taking to eventually land a job in those industries? Is IB really out of the question? Due to my age and lack of resume and experience, is going for an MBA my best and most realistic option or should I be working on landing internships in those industries?

Sorry my post was a little long but I wanted to give as much info as possible so that I could get the best advice possible. Thanks in advance for any helpful information!
