I've been trying out something one morning a week. I try to do a practice painting before any other work, not just to practice skills but to get into the rhythm of the freelance working day. I cannot tell you how hard it can feel to get into the grove of things when working from home, so engaging my brain with something creative that's not to do with normal freelance activities in the morning seems to do the trick!
I don't know if this is something that I'll keep up as a regular occurrence, but for now I find it fun. I've recently started painting flowers in these mornings, mostly because when I'm out walking or traveling in general, I see beautiful flowers and either take a photo of them or take a note of what they look like. They're so nice that I just want to capture them in a painting.
If you would like to see more morning practices or other illustration practices in general!- I post a lot of my progress on my Instagram :)
