I like your opinion. I founded a startup at 40 as a part time job and it was a correct decision during covid19 crisis. My company is quite successful. It takes about 3000 hours to be sustainable. 10000 hours is an overrated term
I posted about my journey in the hacker news post "A disabled 40-year-old person founded a startup and makes a living". Thanks for taking time to read my post. Have a great day
