If there’s one thing I’m good at, it’s being conceited (please don’t miss the irony of that statement). Let me share with you three steps you can follow to be conceited.
1. Isolate yourself from opposing ideologies. Don’t examine any alternatives to your own way of thinking, and whatever you do, don’t look for any truth in what someone else has to say.
2. Seclude yourself from living, breathing human beings. If you can avoid peoples’ felt needs then you don’t have to worry about whether your way of thinking is practical or even helpful. I find it helpful to avoid conversations with strangers.
3. Repeat steps 1 and 2.
I Corinthians 13.4-7 Love is patient and kind; love does not envy or boast; it is not arrogant  or rude. It does not insist on its own way; it is not irritable or resentful;  it does not rejoice at wrongdoing, but rejoices with the truth.  Love bears all things, believes all things, hopes all things, endures all things.
If your way of thinking and living can’t reconcile with these preceding verses, you’re conceited. Knowing is easy. Loving is difficult. Knowledge void of love leads to conceit. But I bet I’m more conceited than you.
