I'll say. It seems that everything I like I either got into accidentally or was a popular thing at one point. Anime was a popular thing back when I was a kid, but I never grew out of it and went to find more.
Not really. Sometimes I will run into difficulties, but I'll often times just use a random idea to build an entire character. Take Garfield for instance. I made him because I accepted a battle request after dropping a hammer on my foot. I wear steel toed boots so don't worry about it hurting. I didn't feel a thing.
And then we have the adult that I'm playing in a Horror RP. I basically just modeled him after myself, with some changes of course. All in all, it just depends on what has happened recently and what kind of RP that it is.
