What career should i choose?

hello i am currently in my first year in college and do not know what career path to get into. My two options are either to become a civil engineer or a sports physical therapist. I think they both make about the same amount of money. and schooling I think is about he same. I had chose civil engineering because my father owns a construction company and i have a lot of knowledge in this field and i know many people in the field, but im not so sure about this field because of the amount of stress and not that good salary. on the other hand , i Love sports and have always wanted to play professionally but i suffered a acl tear in high school and out went my dreams , and it seems being a physical therapist is more laid back then being stressed. i know every job will have its stress bu i work for my fathers company now and i have so much stress already. another problem is my father has his hopes up that i would become a civil engineer and he wants me to but im not sure it would make me happy. i would love to open various physical therapy offices and hope that it would bring me a good salary but i don't know if there is money in that also. im SO confused
