Read Richard Feynman's, "The Pleasure of Finding Things Out"I believe there are many people here doing research on different fields. Research most of the time is very tedious stressful and frustrating. How do you keep yourself motivated to work hard until you get some satisfactory results? and are you willing to sacrifice your mental/physical health to get some results no matter what or at some point you would change your attitude?
This would work. I do a walk sometime during lunchtime, mostly with a colleague, and try to ride my bicycle to work.Actually, having hobbies and outside things that you do can help. While I was working on my Ph.D., I took up the study of formal logic as a hobby. I would work a while, study a while and come back refreshed. Doing things that are healthy also helps. Sitting around for hours, your head gets foggy. I had an adviser once out at one of the national labs who would get up and walk around the lab complex at least twice a day. I started doing it too; when I would get back my head was always clearer. Concentrating on one thing to the exclusion of all else leads to burnout. At least it would for me. And I am not known as lacking focus, for sure!
One might have Asperger's and/or ADHD. ADD/ADHD runs in my family. I didn't let it interfere with my learning, although it was difficult to do lessons or focus on things in which I was not interested.While I was doing my PhD, and I was working on something and stuck, I couldn't think of anything else. That is why I had such a hard times in my PhD, especially I am not that outgoing type of person. So, I would dwell on the problem day and night. I also have a problem in focusing (unlike you) due to suspecting ADHD. Now things are more relaxing since if you don't get something done, I don't lose anything, and thus I don't have the kind of stress I had during my PhD. But still doing research is a huge part of my life and it is boring most of the time, except when you have a glimpse of optimistic results, which will energize me for a while and then fade away, which is usually quick.
For me research is a matter of "finding things out" and I do find it enjoyable or pleasurable, especially when it involves obscure bits on information or knowledge, or things forgotten.
