I know exactly what you mean. In fact, my "word" for this year was ACTION because I always talk so much about what I'm going to do but never do it. However, my procrastination comes from fear of failure. I worry so much about the end result, being criticised or judged and it really holds me back. Well, I'm trying this year and each day it's getting a bit easier! Like you said, you've just got to get started! :)
