Physical Therapist is the proper answer i believe..
I've had plenty of friends get injured and have to go in for physical therapy and complain haha
Answer: because you will know what is good and not good. Research.
Explanation: research the foods you eat if they are not good for your diet don't eat them
#1 try things you are good at
#2 If you are having a hard time trying to do something do it until you get it right
#3 Review all things you are good and bad at and try to practice on the things you are not good at
#4 Practice things you do not feel good at until you feel decent at it
