- another stat for you: most entrepreneurs fail "about twice" before making it, i.e. you'll probably fail 1-3 times for sure before entering the 5% of those who create a profitable business. Trick #1, thus: you can roll the dice several times (consider 2-5 years per "real try").
I've never heard of this stat. Seems like a case of survivorship bias more than anything else.
For every entrepreneur that "made it" on their third try, there are millions who had to declare bankruptcy and set their career back years because their ventures didn't work out.
