You don't have to buy it at all, though. It's free! Looks like OP explained his system below, but it's really just an instantiation of The General System: 1. Try something. 2. If it worked, go back to step 1, and try to do better. 3. If it didn't work, go back to Step 1, and try to do better. (There are some tricky parts to the system, like defining "works" and "better" — but on the other hand, everyone has to define those for themselves anyway.) Also, FWIW, "failure" might not be the most useful way to frame whatever's happening for you. Sometimes, I like to say instead, "an embarrassingly high price to pay for learning a simple lesson... but at least I've learned it now." (Usually, when I frame it that way, it also becomes clear that I passed up many earlier opportunities to buy the lesson for a much cheaper price. And that's sort of a nice realization, too, because it restores a fair bit of agency.)
