Why would a professional gambler, a “career” track with no need for managing anyone but one’s self, want to be hamstrung by the reality and nuance of management? You know (I presume) how exhausting that is.

No, a smart (or even passably well written) professional gambler could present their legitimate skill set for jobs that make use of it.

They also, aside from hard skills (corroborated by good record keeping), would presumably develop or possess at least above average soft skills in the areas of communication, assessing client needs, and negotiating.

They would be terrific lenders, corporate salesmen, insurance investigators, the list goes on and on.
