Looking at what other people did and how that turned out is completely useless because the things that matter are the day-to-day details which you can only get by immersing yourself in the process full-time for a long time. So sharing that data would be worse than useless. At best it would serve to satisfy some prurient interests, and at worst it would cause someone to act on what cannot be anything other than hopelessly incomplete data.
But there is one detail I will share with you: I decided to start not in high tech because I thought it was too risky, but to get my feet wet by starting with less risky investments. So I decided to invest in a real estate development in 2006, thinking that even in a worst case scenario there's an asset there that will be worth something no matter how badly things go wrong.
Like I said in the OP, you will be shocked at how things can fail. (And this is far from my only horror story.)
FWIW, I've also had some winners along the way. I'm not poor, just poorER than I would have been if I'd just put the money in VTI.
