It may not always be wise to start working despite not feeling it. One could burn out that way. Scott H. Young write an article about this recently. https://www.scotthyoung.com/blog/2020/01/13/too-tired/ I have also experienced this. When I got my first job I actually tried to work all the time, besides the occasional breaks, ignoring feelings of tiredness. This got to the point where I was feeling tired pretty much all the time I was awake. Then I concluded I should give into my cravings for purposeless web surfing sometimes.
I wonder how much of this is because of physiological aspects that have to change to keep up with your other lifestyle changes. Brain exercise takes energy, and you might just not used to eating and sleeping enough to maintain that level of exercise.
Agree, the way should be instead how to make myself feel like starting that task. Ask yourself why you are not feeling it, but obviously it’s because there are more fun tasks, so you need to solve why it isn’t fun, and devise a way to make it fun for you. As opposed to treating the task as torture.
