I am strong because I know my weaknesses. Everybody in the world has weakness, so don’t cheat yourself, or pretend that you don’t have weaknesses – normal people have strength and weakness as well.
If you are being asked one day about what is your weakness?! Just tell them by self confidence and your nose up high, that you had them before, but you overcame it now. In turn, the one who asked you the question has also weakness. So If you asked him about what his weaknesses, and lied. By answering by ” no”, it means he is real weak.
Undoubtedly, this person needs a lot of time to discover who he is, as he has got lost inside himself- unable to find his own way. It means, he is not able to trust himself. While the other who knows his strength and weakness, it means that he has a strong character not being feared of what he/she encounters, as he has enough self confidence for facing things.
