I've been working from home since mid-March (twelve weeks so far). I'm very lucky that my employment hasn't been affected by COVID-19 at this stage, and that my job can be done from home.
My creative business is also home-based though, so this means a lot of my time is spent between the same four walls. So every day I aim to go for a walk around my neighbourhood to make sure I get some time outside and some exercise.
Personally I also think it's really important to mix up my visual stimulus - casting my eyes over long distance landscape scenery, close up interesting leaves, different coloured flowers, patterns in fences, etc. It's refreshing and inspiring. I always take my camera in case I see something I want to draw or paint later :)
