I’d rather learn from failures than success.
Also it’s said :
Consider, founders of a previously successfulbusiness have a 30 percent chance of success with their next venture, founders who have failed at a prior business have a 20 percent chance of succeeding versus an 18 percent chance of success for first time entrepreneurs.
It’s “easy” to be successful once.
If you really want a mentor, look for someone that’s been successful more than twice (0.18*0.30=0.054)
