" The desire for balance makes sense. Enough time for everything and everything done in time. It sounds so appealing that just thinking about it makes us feel serene and peaceful. This calm is so real that we just know it’s the way life was meant to be. But it’s not. If you think of balance as the middle, then out of balance is when you’re away from it. Get too far away from the middle and you’re living at the extremes. The problem with living in the middle is that it prevents you from making extraordinary time commitments to anything. In your effort to attend to all things, everything gets shortchanged and nothing gets its due. Sometimes this can be okay and sometimes not. Knowing when to pursue the middle and when to pursue the extremes is in essence the true beginning of wisdom. Extraordinary results are achieved by this negotiation with your time. "
