When writing analyses, one must have a formal tone and use elevated diction and avoid word repetition to keep the analysis from getting stale. Pokemon taught me how to write and argue formally.
I always like it when a new gen comes out and the metagame hasn't been established yet, so any team I build and find success with is mine. I feel happier winning with a team I made by researching what stats a poke had and what it can learn so I could determine its best set and utilize it than I would with a team of the top 6 most used OU pokes. I like the creativity of designing my own sets before it becomes standard to run X with Y. Pokemon taught me that it's not about winning, but about how much you want to win: so much you actually put thought into your team instead of grabbing 6 sweepers.
Pokemon taught me about niches and usefulness. Why is Hippowdon in lower tiers when Tyranitar is in OU and sometimes Ubers? Outclassing. Tyranitar has so many possible movesets that it's almost impossible to just assume what it's running, even whether it's offensive or defensive. I have never heard, however, of an offensive Hippowdon. T-tar has better stats, thus outclassing the hippo.
An extension: why is Jumpluff--an NU or RU poke--used in Ubers (let's just say this is 4th gen; it makes the analogy better)? Niches. Groudon, the only Drought user (again, 4th gen) is in Ubers, activating Jumpluff's Chlorophyll, making it worthwhile.
Now, in any situation when I'm trying to impress anyone, even and especially myself, I look at what my niche is in this group. What am I best at here? In my choir, I can sing the highest of all males in my chest voice, so I try to present that talent to make myself seem impressive. I EV train my Darkrai in Special Attack and Speed because those are the two things it's damn good at. I teach it Dark Void because it's damn good at putting things to sleep.
Tl;dr, Pokemon taught me formal writing and arguing, the increased worth of self-made success, and the applications of usefulness and fulfilling niches in groups.
