One of the consequences of attempting to "juggle elephants" is that we end up doing some of our tasks half way or that we deliver a product or service that is "half baked." More than ever, poor performance is a result of having too much to do and not enough time and focus to deliver.
Lord Chesterfield said, "Whatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads."
Take that little extra time to be thorough. Remove other "acts" from your "circus" to make sure you are delivering a quality performance.
