Should I CONTINUE to play guitar? I've only played for two weeks worth of lessons when I was 15. I'm now 22?

I'm now 22, but I can get creative with band ideas and that the first one I can think of was a band idea for a post-grunge theme. But rock will always be my second favorite, next to real Heavy and Thrash Metal. Bands like the Big Four (Metallica, Megadeth, Slayer, Anthrax) or bands like Judas Preist or Black Sabbath which is traditonal. But my first metal bands were Twisted Sister, Guns N Roses, Motley Crue, Kiss, and Areosmith. I've also liked Quiet Riot alot. But I have so much culture for Death and Thrash Metal, even though I sadly like bands that are considered emo and post-grunge. Should I get sad about it? I listen to all genres, including metal-core or deathcore when it comes to BMTH and Carnifex. But that's about all bands I listen to when it comes to like bands from Anal **** all the way down to bands like Creed. It I guess now just all depends on which bands have more skills or which have energy. Some melodic death is badass, but  I can listen to Creed or something when I'm in a mood for listening to some Creed or Nickelback. That's why I stopped playing guitar, including I have no talent. But I can play air guitar alot. Hahah
