It is always worth while fighting flaws in your character. I've spent quite a bit of time in introspection recently as I am in a ministry transition and have nothing to do but pack my house up and pray. That kind of activity level tends to put you into the world of introspection. I embraced this and found in my life several black spots on my personal character and holiness. The only response is to let the Holy Spirit guide me in correcting these flaws.

I highly recomend this form of personal improvement. It's painful, but you end up liking yourself better on the other side.
