Especially for programmers, designers, engineers out there. Say you are having a day or two when you are just tired. (Went drinking night before, been working hard for 2+ weeks, or watched that movie you didn't need to watch late into the night and now you're tired, etc).
Now comes morning and time to start crunching on heavy problem solving but the brain just wants to zone out.
Is there, a warm up technique that you can use to get yourself back into the mode?
For me presently, it's like jumping into a pool of cold water, just do it FAST and get it over with. I am wondering, for people who are able to maintain solid focus for weeks on end, if they are accustomed to a ritual that helps. (This is similar to my question: What is a good way to begin your work day?) but different because it's not about motivation, it's more about (in the zone type) of mental focus on problem solving; maintained for days (including low focus days).
I may be wrong and I may be still solving the problem in the area of procrastination or motivation. But I'm currently suspecting just the brain being tired, or.. like an attempt at pushing mental endurance of working longer (weeks) and on some days needing a 'warm-up'.
This is the mind being tired enough to not really care about tasks and deadlines.
