Very rewarding profession.
I think the most important skills in preparing to become an OT include a desire to help others, a non-judgmental perspective on the lives, choices and challenges of others, problem-solving and critical thinking skills, flexibility and compassion! You will learn all the technical skills in school (i.e. transfer training, interventions, handling techniques, etc.) however those qualities can help you become the best provider you can be, as well as a good candidate for school programs. Please ask additional questions if you have them! :)
