The first ten things you make are tuition. Nobody gets that money back, and nobody needs to.

Early work is a cost of entry rather than a product. The first attempts are how you buy the information you cannot get any other way, and expecting them to also be good is like expecting your first lesson to earn money. The ten bad things are not a waste, they are the fee.

Count how many you have actually finished rather than started. If the number is under ten, you are still paying the tuition, and the best thing you can do is pay it faster. Make them smaller and make more of them, and stop grading the receipts.
