I can't do everything, but I can't choose. What would you choose?

This year I've become interested in a lot of things. I'm a very musical person and I play the boon. I take lessons once a week and I'm also apart of a trio with two of my friends and we also meet once a week. My boon teacher this year wanted me to be in community orchestra and so I signed up for it. The days of these three things are on Monday, Wednesday, and Friday. School is starting soon and the school play is always in the beginning of the year. I love being in the school plays because I love performing. The drama teacher spoke to me the other day about playing my boon or flute(I used to play flute, but not much anymore, but she knows I did so...) in the play. She sent me the dates of the practices and they will be Tuesday, Wednesday, and Friday from 2:45-5:00. I also signed up for SAT prep which is on Mondays and Wednesdays from 5-6:30 but its only for four weeks. This would conflict with Orchestra from 6:30-9. I guess I could arrive late but then I will be busy from 2:45-9 for four weeks on Wednesday and that doesn't leave a whole lot of time for me to do homework and I have a very difficult schedule this year. I also really want to take piano. I found a teacher but she might not be available, but I keep sending out positive tohughts and I'm praying for it because I REALLY want to learn piano. It's something I've wanted to do for 3 years but never found the time, but I really want to get it done before I graduate high school (I'm going to be a junior this year) Anyway, that's not for certain, but I want to include that too. I just can't decide whether to put myself through hell on wednesday nights for those four weeks. Should I just tough it and risk failing? Or should I choose not to do the play? At this point that's the only thing I'm not committed to. That and piano. I don't know what to do because I really want to do this play (It's Oliver Twist and that was one of my favorite books) but I don't think I can manage staying out until 9pm on Wednesdays with all the homework I'm going to be getting. I need to decide soon. HELP!!!!!
