I found that becoming an actual user of your own system changes the perspective entirely. I had this thing that I was making for myself, and it was not ready, not usable at all, or so I thought.

After giving up on the project I decided to try and actually started using it as if I was a user. I realised that as users, we are used to countless minor issues, and we automatically find ways around that. When you are the creator of something, you sometimes forget that a lot of sloppyness will not be a dealbreaker, and the user will effortlessly work around many of the shortcomings. Obtaining perfection is more about ego at that point.

So trying to actually use it, ignoring that you are the one who made it, and forbidding yourself to make any modifications for a while, can change everything!
