My Whole

Concentration has been defined as "the ability to direct one's thinking in whatever direction one would intend".
I have the ability to concentrate on tasks most of the time. But at other times I can’t focus on the task at hand, my mind keeps returning other issues.
It helps when I’m feeling good physically - i.e. feeling rested, relaxed and comfortable - and my emotions are calm and benevolent, then I tend to be positive about things. This in turn allows me to feel good about what’s going on around me, which makes me more able to concentrate, if only because I don't have to worry about how awful my life is.
Sometimes what I feel responsible for is just too much for me to get my head around. When I think about it, it appears to be beyond my ability to control and I feel helpless. Both contribute to losing concentration because it all feels impossible.
In such circumstances, I need to look for ways of break the task up into smaller discreet parts that feel manageable. Then treat them as individual tasks, summoning up your concentration for each of them separately. It then doesn't need so much effort to fix them all together later on to make a complete whole.
