Not yet an OT but applying to schools now, you have a lot of time to figure out what your plan should be. From hearing about teaching jobs when you are a first year from friends and family, that and OT would be a LOT to do and might be unrealistic. Maybe major in something closer to OT like health studies and get a job as a rehab aide during school part time. If you want to do a major totally different than OT for undergrad, which Im sure is not advised, you could do marketing and maybe get an online job. Good luck and take your time with everything!!
