I find the following helps: - Changing my routine seems to kick off my ability to focus - I have a sit-stand desk. Using it standing seems to help my focus, but changing between sitting and standing can bump my motivation. - For clients starting and stopping a timer helps me focus. - For clients and my own projects I use Pivotal Tracker to order tasks. It helps me break stuff down into smaller parts and to keep track of what I'm doing and helps me to avoid wondering what to do. I use it even though clients have their own project management solutions, I only use it for what I'm doing. - I've never found rewards/punishments to be particularly effective. - Unfortunately (because I'm from the North of England) I find that the better the weather the more motivation I have for just about everything. edit I forgot to mention, fasting helps me focus too, even for long periods. Could just be the change of routine. What I will say is that I've not cured what sounds very much like what you suffer from, just generated ways of dealing with it, more or less.
