Love your neighbor as yourself...self love is important...important enough that God included it along with loving Him with all your heart...and saying "there is no commandment greater than these." So I'm going to use one of my husband's favorite words here..."balance". You have to have balance...don't think more of yourself than you ought to and love yourself so that you can love others. Getting this out of balance can be disastrous for you.
True humility is the total opposite of pride and arrogance...you cannot have those attitudes in your life and treat others the way you should. We need to learn from what has happened in our lives and keep pride from ever sneaking in to do damage.
What's that word again? Balance!
