You can be as arrogant as you wish. But you can't practice arrogant pride and think you will go to heaven when you die. You should consider your eternal destiny. Being proud of one's accomplishments (like getting good grades, achieving a goal) is a good kind of pride. Being arrogant and verbally abusive, thinking more of yourself than you ought, talking down to others, mistreating others are all things that the "wicked" do, and they are bound for destruction, not eternal life. If all you ever want is what you can beg, borrow and steal from this life, then go for it, girl. But if you want an eternity to explore other worlds, make friends with others, have a beautiful mansion on the New Earth, etc., then it's time to swallow your pride, learn some humility, learn to be kind and helpful and polite. In the long run you will have a lot less conflicts in your life if you choose to live a noble life with high moral and behavioral standards.
