Read the details before answering, just a general question, what should I do with my life?

Anyways, thanks for your interest. I am 30 years old have a wife and two kids, make almost 7 figures a year and have numerous investments. I have a PhD with postgrad work.I am part owner and executive in a flourishing drug company that is pretty much self sufficient, I am basically there just to go through the motions and dont really do much there anymore but I somehow find myself working from 7am to 6pm, I see my kids on the weekend and at night but usually we are shuttling them too and from activities which they have a packed schedule, my wife of 12 years and I still have a decent relationship but at times we seem to be growing apart. Lately I feel that my life lacks purpose and direction. Which is odd for me because I am always focused and driven. I was wondering what other peoples takes on this are and any simple advice besides dont work so much.
