Mmm, I really like what he said there. Being weak does indeed mean that you can become strong again... I also want to add to his thought. To me, weakness means an opportunity for remembering kindness, too. When you are weak, you can't help but rely on others. Reaching out, fighting, getting help-- there's a gratitude that comes from all of that. I think, once a bit of that strength is gained, that past weakness becomes kindness (or rather, should become kindness).
So, yes, weakness is definitely something anyone competitive hates, but looking on the bright side, weakness has some merits... right?
