I'm sorry, I think I was unclear and can see why you would take offense. I don't think this was a knock on creating a finance business or anything else - it was specific advice for me and my career path. He was telling me that doing the finance business now would have been the obvious choice or "easy out", rather than tech startups, because it was the industry I grew up with. He was telling me that if I had the balls to consider starting a hedge fund I sure has hell should have the balls to start a tech company.
As I said below, it's likely that I am hyper-sensitive to these issues. I urge you to continue sharing your journey and your stories!
Be careful not to take away credit from yourself, though; in finance, your father may have been able to "open" a door for you, but you would still have to walk through it.
