Limitation is the only way to get anything done. The less one aims to do, the more gets done. By the time the aim becomes to do nothing at all, everything is accomplished.
On a practical level, trying to do too many things at once results in not having enough time for any single one of them. Thus the paradox: the less one is trying to do, the more gets done. At any rate, it’s impossible to do more than one thing at a time. The closer one approaches to the ideal of unity, the more efficient the work becomes. Distraction is dissipation; limitation is focus.
This is not a moral statement but a practical one: limitations free your energy for what matters.
