Yes, I'm 70 and continue to reinvent myself. After high school, I blew up my undergraduate studies because my head wasn't in the game. I took jobs in my 20s that addressed what I thought of as social weaknesses. By my late 20s, through aggressive self study and a couple of college classes, I switched careers and entered the software development world. Again, a lot of time spent on aggressive self study to be competitive with established developers. Realizing in my mid-30s that my lousy undergraduate showing was holding me back, I re-entered school and subsequently completed two masters degrees, an MS and an MBA. The MBA granted me credibility with senior management and propped up my management career. I did that for a few years until I and friend of mine started a consulting/development business, which we did for about 8 years. At that time I was offered a job with a Fortune 500 company that was too good to pass up. Following a series of takeovers, my job morphed repeatedly until, at age 65, the last company bought me out. Now, at 70, I've been accepted as a freshman at a major university to study things for fun, not career prospects. The bottom line, you can always reinvent yourself. It's not always easy, e.g., going back to college while working 50-60 hours per week, but it can be done. All it takes is planning, sacrifice, prioritization, and deferred gratification. In the end, it can be transformative. But, it will always be a hard journey.
