Grab whatever's lying around. Scraps, leftover paint, an old bit of paper, doesn't matter. This is something I started with myself — don't overthink it, and don't think you need the perfect setting or materials to begin. Here's the prompt: don't plan anything. Pick up to 3 colours, no more than that — and make sure at least one is a favourite of yours. Cover a small area of the page with them. That's the whole task. No picture in mind, no "getting it right." Just colour and paper, sitting with it. This is what I mean by working in flow — you're not trying to make something good; you're just starting. And starting is the bit that usually gets stuck. Try it today and come back and tell us — which colours did you pick, and how did it feel to just start without a plan?
