Selling stuff is an extremely outward-focused career though, and it's its own thing. You have to be really careful due to the creeping boiler room effect. You can lose track of who/what you are inwardly very easily, due to almost no attention given your own values, and in effect a strong counter-incentive for attending to your own stuff.

I have career-coached a lot of top sales people and most of them have been very clear that time spent convincing other people is exactly that much less time spent on personal goals, education, etc. For introverts, the #1 complaint is that it focuses you on your weakest side as your career foundation.

Most also ended up gradually substituting sales education for specialty education, without realizing what they were doing, or that they had a choice. So you get people with tremendous, but less-interesting people skills hitting their '40s and going to tech boot camps because that's where their heart was all along.

I had similar experience myself and if I could go back in time I think people skills learned in basic IT work were plenty. Let sales people be sales people, hire them to do sales, and stick to one's own favorite things...otherwise yeah if you like sales, knock yourself out.
