Selection bias is perhaps your problem. The people talking are still trying or succeeded. That said, if you want a story of failure, I spent a year working on a startup idea, spent a large chunk of my savings and ended up scrapping it, it never got finished or even launched. Much of the reason for spending so much time on that one idea was because I took a Master's degree in Entrepreneurship and it was part of the curriculum to write a business plan and try and start a company. If I had a second chance, I would have saved 5 figures worth of savings and done it a lot leaner and pivoted to other ideas which had a better chance. However, the way the program was structured, there was a certain lock-in which meant degree or startup in a sense.
