If you're doing this too, here's my advice to you:
Take pictures like they're the last ones you'll ever make, like this is your sole legacy. Take pictures like you're going to be killed if they're not good enough. At least make a picture like you're going to frame it and try to sell it. Stop making tests.
At least for a while. You gotta learn, too, but you gotta do something with what you've learned.
