Some of my favorites from her (paraphrased):
- Fuel it with something new.
- Get a pattern going.
- Get some organization going.
- Keep lots of sketch/notebooks around for random thoughts.
- Pick something to focus on.
- Practice, practice, practice.
A couple of my own:
- Look at other peoples work to get fresh perspectives and ideas.
- Look at your old work and see how you can improve it now.
- Go for a walk down to the local shops and find something you can improve.
