Every big fall I had ended up being a huge improvement in my life in hindsight, after a year or two. You couldn't have foreseen these issues and should feel proud of the experience you had. I hope everything works out well for you.
I appreciate the sympathy, really. The thing that I probably regret the most is really the time invested. That's the only thing I can't make up for. Even if I try to look back fondly of the learning experience I'm still severely burnt by it.
What I did in fact learn was to give absolutely tons of respect for people who pull this off. There's a lot of trash talk articles about Peloton and other struggling hardware companies but they have no clue how freaking difficult it is. Now at least I can say I do.
The future is still bright. I was lucky enough to have two business going and the second one is a thriving consulting software company. Sorry if it looked like I was in a dire situation personally. Not really the case.
