Ignorance is the lack of knowledge on a particular issue. Ignorance is the worst thing that could ever happen to anyone. Ignorance will make you look foolish, it will deprive you of your peace of mind, it will make you call a toad a frog and a snail a scorpion. It will make others exploits you. Therefore strive to know all you need to know so that you won't feel ridiculed and be ridiculed. And if you know, please, get others informed but not with pride and you will be blessed.
