You seem to be someone who can use the collective intelligence to produce better work. 

To create your Service Design Principles Library I suggest you schedule from time to time a coffee with a friend to chat about this. Take some sticky notes, take a few notes and then write together.

Your strength and resources

1. You have a good network of friends and peers

2. You have the time to have one to one conversations

3. You have a bit of money to treat friends or colleagues to a hot chocolate

What you might lack

1. You are not process driven

2. You have difficulty formulating an idea

How to go further

1. Read The Wisdom of Crowds

2. Make a list of friends or colleagues with whom you have smart conversations

3. Send a message to three of them for a conversation about Service Design Principles
