If getting VC funding is considered partly as a sales job, then Bill Porter's story may be interesting. Consistency in 'top selling' requires qualities like determination & efforts. Natural born 'attractive people' generally are not inclined to put in that extra effort just because they, in their lives so far, probably didn't need to.

Wiki: Bill Porter born with cerebral palsy, was unable to gain employment, but refused to go on disability. Porter eventually convinced Watkins Incorporated to give him a door-to-door salesman job, selling its products on a seven-mile route in the Portland area. He eventually became the top seller for the company.
