As of today I am changing my daily working routine.
I used to do a 45:15 routine and it worked pretty well for me. But now, since I have only 4 to 5 hours of pure work time I've decided to dedicate it mainly to sketching and everything that has to do with it. No more jumping from one subject to another and no more long daily To do lists.
And the rest will be done whenever it will be done.
New situation - new routine.
