Think of if you need a designer or a decorator?
When I'm starting with a project - I'm trying to deeply understand the product or the company I'm working for. And it's not some cliché I've read on the internet. The same way as a good actor would be preparing himself for a new role, I'm putting myself in the user's skin and trying to figure out what he might need and how he would feel. And then - just letting the design follow. Everything else is a decoration.
Therefore, people don’t give a shit about the design! If they notice it even less while using the product - the design is better. So, the only perspective I have while making things, is user's perspective.
