What Kevin said.
I read something about time management by Anthony Bloom the other day that stuck with me. He said that the problem isn't that time drags or moves too quickly ... because time, after all, unfolds minute by at the same pace. (Yeah, bear with me here, you physicist types! Consider this a metaphor if you must.

) Bloom says that the problem is always that we live nostaligically in the past, or try to hurry madly to stay ahead of the curve ... staying an inch ahead of time. And in either case, the problem of balance is simply that we're not living entirely, wholly, in the present. In the instant within time where we actually are at any point.
Bloom suggested that being fully and totally immersed in our task of the moment, whatever the task, will typically lead to it being done better ... with less re-doing. And give us more "leisure" moments. Because those moments between tasks will be still, will be actually experienced, rather than be wasted worrying about a future we can't speed up, or a disappearing past we can't slow down.
