grace, and grace again

I have always been on the receiving end of grace, especially from the older folks in my life, or from guy players who are much better than I am. Now, I'm called on to show grace to others, especially those younger in age and/or in maturity, and it's much more difficult than I ever imagined it to be.

Over the past few months, I've been thinking about quitting, and I still think about it a few times a week. What's going on? What will God teach me through this time?
