Some stuff I've done in the past: - Creating prints and selling them in local shops - Designing gig posters for local promoters - Starting a physical product (I run Wax & Stamp. Was a hell of a lot easier than I thought...)

Those are the design related things, although I find side projects that tap into your passions are super good for flexing your creative muscles. I've had bands, produced and directed theatre, ran a club night and loads of other stuff as side projects. Anything to help keep the juices flowing
