The line to crash and burn is filled with people thinking they are going to do something they have never done before and know nothing about but some of them will make it. 5 or 6 failed scooter rental business means 5 or 6 pioneers failed to think it through.
A shoe repair shop on an island of barefoot people was laughable but now folks are wearing shoes and scooter rental to an island with out roads was doomed but now we have roads. I can't say anyone has a bad idea but their idea may have bad timing.
My thinking is attitude is the key to success but timing is a large factor.
