I use my personal core values as decision guidelines that keep me congruent to myself, and out of problems.
Here are mine with brief descriptions:
Creativity - I have to remind myself that I need to take that extra step to make my material compelling so I can intrigue, entertain, and connect with my audience.
Impact - Like most entrepreneurs, I see potential everywhere. This value reminds me to disregard when my brain is saying: "I can do that!" and instead ask the question: "Should I do that?"
Truth - I make it clear in conversation and in writing that truth is necessary in my world, no matter how painful.
