For sure weakness can make us to be a better person, because we will want to upgrade from our weakness and correct our weakness.

So the more we try, the more we learn and have more knowledge, so we in the process will be a perfect and better person.

have met a couple of people who believe that they are flawless. Saying that you have no weakness in any aspect, simply means you claiming to be perfect, and we are made to believe that nobody is perfect, perharps except the creator of all.

No body that do not have weakness, Is just that the way we manage it is matter alot. And the difference is that my own weakness can be your own perfect.

So everybody is perfect but only God, thought some people believe they are perfect because they know how to manage their weakness and they do not face any problem.

So they believe they are better, but until they see another person who is far better than them,than they will now that what they call better is another person little perfect.
