I had lunch with a good friend from high school who is a successful businessman living in Mainland China. He gave some sound business advice that is worth further consideration.
1) Since making a profit is not my primary goal, to reach out to a wider audience I probably need to step up my marketing effort and budget. I need to accept the fact that I may have to incur a loss initially in order to stand a chance for a greater success.
2) The printing cost is too high. I should try to reduce it because it limits how many promotional copies of my book I can offer.
