OMG. I FEEL THIS SO HARD. What I do is draw down a quick sketch that I can refine later and then get back to the things I absolutely need to work on
That is a great idea too, I have done it with some things
Yeah, i learned that keeping a 'list' just doesnt work because when the picture is in your mind, words just do not do it justice XD And then going back to it later, 9 times out of 10, i allllways forget what it looked like in my head when i thought it up XD So little sketches/thumbnails do the trick
Put those ideas on the back of your head and get your priorities in first
Put down all your ideas on a list and come back to them later to see which ones you still feel motivated to do.
make a schedule
