Erich: Yes. Whenever it occurs to you. Just that in itself is a good thing to remember.
Therefore, in terms of homework, you don't have to remember to do it from now on. But, if it occurs to you — WHEN it occurs to you — that is the exact moment you should be doing it.
When it occurs to you that is the Universe tapping you on the shoulder, saying, "Pssst... do the homework."
So, blow off having to remember to do anything.
But, increasingly, be willing. When it occurs to you, get it. "Oh yeah! OK. Right now is the exact moment to do the homework."
