to quit or not

I'm off to 11am mass in just a moment. I do two volunteer gigs at my parish. I'm up for one of the gigs today. Truthfully, I don't think I've been all that great at them in the past year. Not too bad, I don't think, but not great either. It's just my opinion, I haven't sought the perceptions of others. I've been wondering whether I should quit either or both. I haven't jumped to any conclusions; it's just been on my mind. I have to volunteer in something, so if not these two things, what else? hmm...
