I'm probably the outlier here for a variety of reasons. I oversee a real estate and private equity portfolio with a market value of just under $2B - I'm 60, so have been at this awhile. My education would not indicate anything relative to my position, but I attribute most of my success to hard work, luck and a few strategic moves - the same things that lead to my success as a competitive runner back in the day. Here you go:
Education - State school - bachelor's degree in Geophysics. Graduated at a bad time in the energy industry. Had a job for 6 months and was laid off, then not a nibble of opportunity in the industry in an energy town.
Moved and started over - Moved to a growing and dynamic city and convinced a land development company to hire me as a 'grunt' to learn the business.
Actively pursued personal growth opportunities even when that meant physically moving to other cities/states or economically lateral moves to other companies. Some of those lateral moves did not prove out immediately, but again, with hard work, eventually proved beneficial. Gained direct knowledge in large-scale land development and homebuilding. Then moved to a Wall Street based private equity group that was involved in all facets of real estate - development, construction, income properties/management, etc. Thankfully I was located out west and not in New York.
A formal education in business would have been very helpful, but that did not happen. More the school of hard knocks. I jokingly say to people that I have a GSD degree. I Get Sh*t Done.
Along the way I evolved into becoming a good people manager. I try to hire folks who are good at what they do, are a lot smarter than me and most importantly are a fit with our team.
