Last thing first: I do everything on my cellphone. No editing software on it. If I need to put a head on something, I Google whose head I want to use, but I add the words "transparent" and "PNG". It's not like the software I used when my computer was hooked to the Internet, but it gets my point across.
Meetings? Had several a month when I was a frosh. Wasn't a big clubber, but I was involved in the school newspaper. It was more than just tossing around ideas, but how to take four blank white pages and turn them into something readable. Lead stories. Sports scores. Humor articles. Where to put them. I was always on page 2, as the humor writer, but people glanced at page one, then went straight to what I wrote, but it was a team effort. Join a club at school. The interaction will pay off in later life when you have to deal with workplace issues.
Gamer memes. You're right, they don't get much attention outside the game arena. It's like being the captain of the chess club team. In chess matches, you're on the top, but in the real world of high school, chess captain is rarely BMOC. Look at the turnout for interscholastic chess matches. Or even track. I glance at gamer memes because it's a foreign language to me. There are too many games. I've yet to see memes about Monopoly, Game of Life, or Sorry. Occasionally I'll see a Pacman pie chart. I lost track of Pokemon in the second generation. No, gamer memes have a small following. But that's your thing. Good. Now spread out and increase your circle of interests. You're learning to build airplanes? Do memes on some of the different models of planes. Pick the unusual ones. The flying wing or the flying pancake. Might get some extra credit
