You sort of proved his point. Your preference for working alone is because you avoid being in a team.
That's quite an assumption to make. We could easily turn it on its head: My avoidance of being in a team is because of my preference for working alone.
I might indeed be terrible in a team, and sadly go off alone. I might be terrible in a team, and yet happily go off alone. I might be terrible in a team, because I enjoy being alone so much more, and so I rarely get any experience with being in a team. (And when I do, I might barely put in any effort because I find it so tedious and unpleasant compared to my preferred manner of working).
If I know I'm happy doing A, and there is a disjoint activity B, then naturally my tendency to A will reduce my time spent doing B. There may or may not be correlation.
>I do know that I'm terrible in a team and prefer working alone.
It's certainly not 'quite' an assumption.
>Dude I absolutely love being alone
>"Relaxing", "exciting", and "interesting also apply
I feel it becomes elevated to "quite" an assumption.
My team considers me a great team worker. Some say stuff like motivating, leadership and mentor in my reviews. That's the extrinsic perspective. Intrinsically I love the sense of accomplishment I get from my own contributions. In comparison to the senseless bickering the team does I see my code, documentation and conversation as pithy and efficient. I know enough to keep these kinds of thoughts to myself. Some in the team don't. It tends to make them look arrogant and haughty.
By your logic, someone who prefers leisure over work must apparently avoid work.
