Does muscles make me strong? I may look more attractive, be able to lift heavier stuff, and do more damage in a fight... but I may still feel sad, still not be able to talk to the girl I love, and still get hurt in a fight.
Does knowledge make me strong? I may know more than anyone else, be able to find a solution for every problem, and get the job I always wanted to have... but I still might have no friends, still not get a result without flaws, and still get bullied at work.
Does wealth make me strong? I may have a big house with garden around, be able to hire people for every task I have and buy anything I ever want... but I still may feel lonely around, still not stop people from leaving me, and still not get rid of feeling emptiness inside.
*So is there really nothing that can make me strong?
If you ask the wrong question, you may never find the right answer.
