Head Problems

So it seems as if I can't get my head around the idea of selling things I make. For one, I don't think what I make is good enough to charge people for it. I made a second video of other cards I made, and instead of taking pics and posting them here on my blog for sale, I simply said that if you like one, let me know. My mindset is such that I think it would be nicer to give away my cards rather than sell them. Am I a lost cause? Anyway, I will still make my new piles of cards.
