"Sometimes, I feel that life is passing me by, not slowly either, but with ropes of steam and spark-spattered wheels and a hoarse roar of power or terror. It's passing, yet I'm the one who's doing all the moving."
~ Martin Amis ~
Extreme momentum and efficiency is possible in relatively short bursts- a few days, a week. But we cannot push on at that pace ad infinitum and expect to have any kind of quality of life. We have to allow for periods of down time and relaxation. They may not be possible when we have a cumulative influx of work, but we have to make time for them somehow, or else we will crash and burn.
I work hard in phases, and then take time to rest and relax.
