If I could be anything... I'd be a (successful) TV writer!

Yeah, I know (*eyerolls*, right?) But, you get to make up fun stuff. Make characters say silly or dramatic things that you could never say in real life.
Get paid well. Work in a team to figure out the story arc for each season. I've read from some writers that they'll actually take the writing team and act out things, to see if they think it would work (which sounds insanely fun to me!).

Plus, if you do well and move up, you get to create your own show and be a showrunner, which sounds insanely stressful, but really cool. (Compared to my office job where if I do really well, somebody might want me to become a team lead - gasp! - or a manger, neither of which is particularly fun or interesting!) The showrunner is in charge of *everything*, like the CEO for a TV show - they get to pick who directs the episodes, direct the storylines, hire their writing team, hire the people who do costumes and lighting, etc.

(This is different than in movies. In movies, the writer writes a script - but then the director takes over and makes all the big decisions. sometimes the script is given to another writer to edit! TV writers get to "own" a lot more of the process!)

I also kind of love TV... more than I should I bet it would be a blast as a career!
