Reading ten books on discipline is also a great way to avoid being disciplined.

Learning about a thing produces almost the same satisfaction as doing it, and it is far safer, because nothing can fail while you are still preparing. That is what makes research such an effective hiding place. You stay busy, you feel serious, and the actual attempt keeps getting scheduled for once you understand it properly.

Close the book and do the smallest version today. One session, one page, one call. You already know enough to start badly, and starting badly is the only route to knowing what the next book should have been about.
