What did you let go of (habits, relationships, attitudes, clutter) that was no longer serving you?
It's an ongoing process, but I think I'm doing well at letting go of the need to have my work and my existence validated by my audience and by the people in my life. Like Seth Godin says, "If the kids in the back of the bus/audience/store don't get it (or don't get you) it's their loss. Focus on those that want to celebrate the work you do instead." It's hard to put into practise, but I constantly remind myself of it.
