picking subjects is kinda torture for me

So I've been really looking forward to this elective in the coming school year, right? its like superrr advanced and you have to travel for it so theres super selective choosing. its also my last chance to do it this year. so in order to get into it, I would have to drop one of my favorite electives, theater, to get into it. so I weigh the pros and cons and I guess I could just join this year's play, instead of taking the year long class and i'd be alright with that because I can keep doing theater in highschool but I cant do this class in it. so i write this boring ass proffessional sounding email to the counciler, and she's happy to do it. I'm not sure if I'm gonna regret this, or if I will even do theater in highschool, but I think it's best for me. I'm super interested in engineering and this class has exactly that. plus theres a competition and you could even go to washington D.C. for internationals. I really like theater but I think I'll like this more. I can't wait for this year.
