I like jugglers. I’ve seen professional clowns juggle at the circus and executives juggle at the office. The execs call it time management or maximizing efficiency but the tasks are very similar. The definition of juggle is “cope with by adroitly balancing.” You may balance bowling pins or projects by constantly reprioritizing in order not to drop anything. The interesting fact about this activity is that no matter how many things you juggle, you only have your hands on two things at any given time. The rest are in the air, on your desk, or they get dropped.
Knowing your limits makes a better performance for every one.
