Who is it for?
Who is making it?
If it’s for someone like you, that’s easy. Go ahead and do it. If it’s not for someone like you, then you need to go on to question three:
How empathetic is the person making it?
The best design project is often for young people to make something for people they understand. They build some confidence. See something become reality, and, most importantly, realize the need for empathy. Because even when you’re making something for someone like you, it’s never a perfect match. The need for empathy is obviated when you create.
Once you have the skill of empathy, now you make anything. Your story and experience no longer limit your imagination.
