But what if I have a problem I don't know how to solve?
Innovative designers persevere through their open-ended problems no matter what.
Part of being an innovative designer is reaching out to others for help when you're stuck. Design is a process: you can't expect to know everything right away.
So you're saying innovative designers are people who're brave enough to see a problem, design a plan using creativity and imagination, and persevere through the process? Wow, I can be an innovative designer!
