I'm not sure what I should do for a career.?

I love to create and design things and then build them. I also am very good with my hands. My dad is a finishing carpenter and I like to go to work with him and build cabinets and that kind of things. I am taking construction at school right now and I have built a tv cabinet and got 100% on it. I got an award for the tv cabinet last year from my school. I used to think that I would like to become an engineer of some sort but I just started grade 11 physics this semester and im finding it quite hard and as I understand, engineering has a lot of physics. I'm a smart kid with about an 85% average and there is no question that I want to go to university, but I do not know what to take.
