Yep, often when we don't find the energy and motivation to do something, there's something wrong that needs fixing. Depression, the work being pointless, FOMO and other desires that should be addressed. Work as escapism ("start sloppy until the task has all your attention") works sometimes, but it's not really victory over procrastination nor even desirable.
wish that worked for me.
one thing that kept me going without effort was "Duolinguo". this clever language learning app has a points system and system of leagues where you move up if you are among the first 10 in a cohort. for competitive persons like me it works very well. i am working my language skills first thing in the morning and last at night, and anywhere in between.
the idea is being in a community of like minded people stimulates you.
How about when you dont feel like working, simply don't work. Do something you feel like and then work when you feel like it again.
