According to your physical condition, it is suggested that you choose a major that requires little physical strength, can be completed independently in the future, and does not need to go out often, such as computer software engineering (programming), e-commerce, accounting, and engineering cost. Especially the project cost is the most suitable. After graduating from the university majoring in engineering cost, first take the examination of cost engineers, and then find a cost firm. You can usually finish your work online at home. E-commerce can also do it. You can sell it to people who open websites online or stay at home. The above is for reference only.
