Working as a florist or phlebotomist...?

So I planned to do a phlebotomy course at my college this fall, like August, and was really into it and ready to do it. But my current job right now is working at the Customer Service Supervisor at a grocery store. I have recently been helping out the floral departement for Easter and Mother's Day and really have shown an interest in it and am actually pretty good. The florist at my store thinks I would make a great florist. She knows some corporate people and said she would put in a good word for me if they ever needed a florist at maybe another store. I was very intrigued by that, never having thought about it before. This totally had me rethinking my plans. Suddenly drawing blood from someone didn't seem so interesting anymore. I really enjoyed working in the floral department; it just didn't feel like work and it was fun. Not sure what I should do anymore. Anybody got suggestions, maybe your opinion if you were in this situation?
