I really like being able to focus on one activity and only that for a prolonged period of time. I could spend days on end doing one type of activity as I feel that the longer I focus on it, the easier it becomes doing it because I sink into it and become absorbed by it. It feels like a locomotive picking up momentum and wanting to exploit it as much as possible rather than having to step on the brakes and change the tracks.
Conversely, I am pretty bad when it comes to shifting from one activity to another. It almost causes mental pain to have to shift and I see it as a logistical inefficiency. Examples include shifting between projects in the same day at work, shifting between types of work when I do home improvements (which I try to manage by scheduling so as to minimize shuffling because I have no boss there), shifting from work to home activities and vice versa, getting out of bed on weekends (transitioning that often takes hours) etc. Also takes me forever to get ready when I need to go somewhere.
Needless to say, life activities are diverse and complex and doing just one thing is not realistic. Therefore, it is good to be mentally agile and be able to transition from one chore to another quicker and more painlessly. Could it be that I am just lazy and looking to exploit the momentum to the greatest extent possible (which has its advantages because lazy people often devise clever solutions to be able to do less work)? I am looking for suggestions how to be quicker in this regard.
