A Lost Soul

I’m confused, lost and in dire need of help… I am an active duty military member that graduated from a service academy. I stumbled upon some luck and have had the chance to run a $100M budget and gain finance experience in a deployed location in my three years of service. As I approach my eligibility to separate from the service, I am weighing several options and would like some advice on what would posture me for future success. I can a) attend law school through the military or with my GI Bill (have applied to several T10’s, been admitted to some T20’s, would like to specialize in business/corporate law or estate) and will incur a six year commitment if I do it through the military, b) attend a PhD in Economics program through the military (would shoot for a T20 school, would like to specialize in Financial Economics) or c) Leave the military and look to start in an analyst position and work my bag off. I also have an MBA from a run of the mill state school. Would a post-MBA program like Thunderbird help with placement (I could use my GI Bill to fund it)? Sorry clearly I am a scatterbrain and have no idea what I am doing but love the thought of working on Wall Street and am certainly willing to put in the time and work required.
