Egotism
A very bad trait that creeps up on you bit by bit until it gets you. It will spoil many things in you, even your piety and goodness can get damaged. Egotism can bring about arrogance and make you look down at others. Egotism and arrogance will stop you from listening to others, and you’ll be deprived of other people’s advice and opinions. You’ll practically be all alone by yourself.
