It doesn't take much to make a workspace feel personal and inspiring. Just keep things few things in mind and you'll be all set:
1. Remove clutter (cluttered space, cluttered mind)
2. Only allow things in there that will inspire or help motivate you towards your goals.
3. Decorate it with intention with pieces that bring you joy! (bonus points if you're supporting local artisans!)
4. Stating the obviouse here, but make sure everything has a place. When you leave your work mode, leave it fresh and ready for the next day!
