So i do cosplay from time to time as well, started in 2011 with it, and figuring out which kind of characters i like to cosplay in the first years basically.
Once i found the kind of characters i like to cosplay, i stopped getting lots of cosplay and fucussed on perfectioning the ones that i really want to cosplay more often. this was around 2015.
I don't go to much anime cons at all (one a year is my average).
