There are so many feel good stories out there lately about various people quitting their jobs and succeeding at running their own businesses or investing. For some reason very few people share their stories of business and investment failures.
Please share your stories of business/ investment failure, what the lesson was, and how much money (roughly) the experience costed you.
I'll share mine first. Started working Feb 2007, first share purchase of the big 4 banks in 2008. Hit the financial crisis, lost about $20000 in 2 weeks (especially in NAB). Sold everything, closed my Commsec trading account. Lesson: with my very limited knowledge in shares, buying and selling shares is like placing bets at a casino, it's just gambling (for someone like me).
