Do what your best at. And if your not good at any one thing, pick one thing that you enjoy and get really good at it or something related to that subject. Take a step back and think why do you like it and that might open up some options.
If you only decide to do a so so job, you’ll likely be forced to do more of what you don’t like doing. That being said, when the going gets rough, don’t quit unless something is wrong or immoral. Approach each opportunity as a learning experience, because your attitude will take you further in life than any subject you learn in school.
