Instant feedback.

I think everybody dislikes being busy and having too much on their plate. 

The one good thing about being busy is that it provides instant feedback.

When you're busy, it's easy to see what you prioritize.
When you're overworked, it's easy to see your main neurosis.
When you're tired, it's easy to see how you handle negative emotions.
When you have no time, it is easy to see what you yearn for.

If you had nothing to do with your day- no appointments, no interactions, no stress- you would have no feedback for your practice. 

It can be difficult dealing with the intensity of our lives, but we have the advantage of using that intensity as a catalyst for our practice.  We have the advantage of using our life, as it is right now, as a means of accomplishment.
