As human beings we have our weaknesses and our strength and that's what makes us who we are. You cannot have strength without weakness, everyone have weaknesses and strengths because they are what keeps us going.
No matter how perfect a human is how strong the person is, you get to understand or know that that particular person you think is perfect actually have weaknesses and very bad one, like the ones that can actually pull the person down you know.
Different people have different weaknesses and strength and that's what makes us who we are; our weaknesses and strengths.
some people are good at hiding their weaknesses that you might think this person does not have any weakness, the person is perfect but when you look deep inside get to understand this person you will know that they truly have weaknesses, I mean no human is complete without their strengths and weaknesses, I believe so.
It is good to plan for a long time investment the one that can cover us when we get old and tired of working when we retire when we are weak, it is good to at least work now that we have our strength to reap the fruit of our labour when we are weam.
