Stop reading business books, and start DOING instead
I think this may be related to my procrastination but Im now much more organized and focused than I ever was. Before I'd spend to much time planning, I wanted to do everything the proper way, as in "best practice". I'd look for books on how to "design better", "manage my time better", "book more gigs", "how to develop my brand"... the list goes on.
In the end I really don't think any of these books helped that much. I had better success, doing and learning on the way. If you find yourself constantly reading and not progressing on your project you may want to put down those books and resources and just start doing, just start grinding.
