The problem isn't ideas. It's putting the phone down and picking up the drawing tools.
I'm quite literally in no position to criticise, but I'd like to brainstorm some ideas with you. I struggle with this too, but have managed to make some progress over the years.
Do you take notes for work or something where you could scratch out a concept or two in between tasks? Would an app/phone timer like Lock Me Out help get your phone time down to a level you're happier with?
This kind of stuff has worked for me anyway. Not to say it isn't still a challenge
A complete lack of organization and an air conditioner that hasn't worked in three years. It's frequently been 87 to 89 in my house for over a month now. It kills motivation to move. But I did just go outside and remove all the 4 foot tall grass from my brick patio. So I have that going for me. Which is nice.
I need to draw monsters that do yardwork. They work outside. Elves make shoes inside. Goblins prune and edge.
