One huge fault in most of humanity is Doubt. But what exactly is doubt? Doubt is when you do not have trust in something. If you are doubtful about something; you have next to no confidence. If one person in a relationship has doubt; goodbye relationship. I'm just going to go full brawl and just quote this from my Little Black Book of Poems;
"Why is it that humanity is always so fragile? Say, for example somebody does something wrong, in a back-stabbing method. Perhaps this person realised their mistake and has learnt from it. Humanity thrives upon mistakes; but shuns them so. In order to increase the rate of which you learn, you need to make more mistakes. Mistakes, mishaps and errors are the best way to learn. The new world is a lie."
Humanity needs to realise this, but are ignorant of one person's morality and emotions. Whats a human without emotions? Emotions are based upon opinions and opinions keep everyone individual. Without individuality, we have conformity. The world is falling back in to bad habits.
