What's important is if we do our best at this moment. If you're playing tennis, you try to play this one shot well, that's all. It's not necessary to worry about the result. If you're building a house, mix the cement well. If you're having lunch, eat something rich in quality rather then quantity. Quality can be a slice of wholemeal bread eaten in peace rather than a four-course meal swallowed unconsciously in haste (watch out not to choke!). Don't rush from good to better. Also taking a good rest is part of excellence. What happens when nothing happens? Do not avoid the void. Excellence is intelligence. Excellence means not getting hypnotized by despair and fear of the fragmentary perception of thought. Excellence is Unitary Perception.
