These are rules many designers live by, daily (even if they don’t realize it because they are busy making, not analyzing). My boss’ boss’ boss has a set of rules he likes the XD designers at Adobe to follow which are, not surprisingly, similar to Sister Corita Kent’s inspired rules below:

1. Find a place you trust and then try trusting it for a while.
2, General duties of a student: pull everything out of your teacher, pull everything out of your fellow students.
3. General duties of a teacher: pull everything out of your students.
4. Consider everything an experiment.
5. Be self-disciplined. This means finding someone wise or smart and choosing to follow them. To be disciplined is to follow in a good way. To be self-disciplined is to follow in a better way.
6. Nothing is a mistake. There is no win and no fail. There is only make.
7. THE ONLY RULE IS WORK. If you work it will lead to something. It’s the people who do all of the work all the time who eventually catch on to things.
8. Don’t try to create and analyse at the same time. They’re different processes.
9. Be happy whenever you can manage it. Enjoy yourself. It’s lighter than you think.
10. “We’re breaking all of the rules. Even our own rules. And how do we do that? By leaving plenty of room for X quantities.” - John Cage.

Helpful hints: Always be around. Come or go to everything always. Go to classes. Read anything you can get your hands on. Look at movies carefully often. Save everything, it might come in handy later.
