Sin of Pride means believing yourself to be better than God, and to a lesser extent overestimating yourself. For example, building a tower which will reach heavens, or thinking you can lift 500 kilos over your head. Dont take a loan to buy a car which is more expensive than your house. Simple stuff like that.
It does not mean that you should never feel good about yourself, and that you are always worse than a fucking cheap jew whore. And even more, it does not mean that everyone is exactly the same, even if one man rapes and eats children and other tries to stop him.
