Productivity books / systems etc

After some therapy for various things, am feeling better and trying to get back on track. A big thing my therapist said to start with now we are coming to an end is leading action and getting myself planned up throughout the week.

Am looking for a a book or two about productivity that are really based on the practical side. Some kind of productivity system or method that I can work through and input my own tasks into etc. I am trying to find a job + plan in time for my hobbies + work out + just generally start from the ground up so, I guess I'm looking for something general or maybe something creativity based or similar.

Am happy to do the reading nd prefer methods that are away from the phone, bit more manual. I think something that is at the core for me is that I am looking to create routine in my life. The work I do get is very ad hoc so i'm trying to find something that doesnt feel like its gone out the window if i miss a day?
