The founder of a company I used to work for was a compulsive penny pincher and
Was known to regularly take flight credits when they were offered even though he ran a company worth hundreds of millions. He also had a team of maintenance guys that were in charge of fixing up random crap he bough that was “a good deal” and make it useable.
The more I learn about people who are uber successful the weirder they are. Pretty sure you have to have an unhealthy level of obsession to do what’s necessary to get there.
