At one point I felt like I was stuck with one style. My hand would automatically draw the same shape as a start. To counter this I took a piece of paper and covered it in scribbles and lines blindly. Turned the paper 90 degrees and did the same procedure, took an eraser and blindly randomly erased here and there then drew lines on top of that until the paper was covered in a mess of lines. Then I sat and looked into the mess and saw figures appear. I enhanced them by removing lines around them and drawing them to be more visible. trust me a lot of fun new figures and ideas came from that. And I agree, one should at least try to always get an idea down when it comes, otherwise you end up losing it later. Love you work btw.
That is a SMART way to be. Alot of times ideas can go to waste if you don't act on them fast. That said I shall play devil advocate and say if you do such too much you get get too little butter for to much toast snydrome and your work collectvely suffers. Ultimately you have to figure out how much work to idea ratio you can manage and find the balance that works for you
