Introspecting, the way I remember this is that 1 is a simple number, and type 1 errors are errors that you make by being stupid in a simple way, namely by being gullible. 2 is a more sophisticated number, and type 2 errors are ones you make by being too skeptical, which is a more sophisticated type of stupidity. I do most simple memorization (e.g. memorizing differentiation rules) with this strategy of “rationalizing why the answer makes sense”. I think your method is probably better for most people, though.
