But designers don't start with a blank canvas. They wander about the topoi, observing what others have already made.
Search for models. Place relevant items on your workspace.
Be playful, keep trying, don't be afraid to fail
Don't wait till the last minute. Grow your design over time. Build. Sleep. Build. Get Feedback. Redesign. Sleep. Build. Feedback. Sleep. Repeat. I solve most of my design problems while I am sleeping.
