Is this too ambitious of me?

I already can play guitar, not as good as I want, but I'm getting there and I'm going to get lessons. I also play first chair for the Clarinet, and I play the piano, I'm terrible at it, but I'm taking lessons. I want to play the Cello, I've always tried to hear for the Cello in Sinfonietta's, because they are so dramatic sounding, they are beautiful, but lately I've finally took the courage to actually go with my interest, and I'm saving up for a Cello. Is this too much? Piano, Guitar, Clarinet? And the odd thing is, I do not want music to be my profession, you would think that since I have such a pion for it that I would wat to do it as a career, but I actually want to be a Prosecuting Attorney.
