Your pride is a monster and if you don't learn to control it that monster will eat you.
Pride is like food, a healthy diet of pride is necessary. Overindulge and your head gets fat and useless.
Pride is a very useful monster to keep at your heels. to keep you stepping along sharply towards *blank*, but it can and does grow out of control.
I see it as the other side of the humility coin. You don't need one or the other. You need both.
