Thank you both for your replies.
I agree that introspection is a virtue, as is being so dedicated to improving my character and my life.
Where it becomes an issue is when I seize on the latest thing I want to change/improve -- it's always something; in this case, ironically, it's focus -- and think constantly about how to practice it and improve it, and how it affects me.
Don't get me wrong, I do very well in my career. But I could do so much BETTER if -- for example -- when I'm sitting in on a meeting at work, I could be 110% focused on what's being said, on what's going on, etc...... rather than drifting intermittently to thoughts of myself, my level of focus, my values, and so on.
The point is that I like being able to introspect so well, but WHILE I'm engaging in any activity -- when I'm in meetings at work, interacting with friends, or in martial arts class -- I'd like to be able to have my mind FULLY focused "out", on the task/activity at hand, and not diverted with thoughts of itself.
I guess that now that I've identified my focus as an issue, I can work to improve it every day in every situation. I was just wondering if anybody was familiar with this sort of problem, or had any advice or guidance.
Thanks.
