I was stone broke, having worked two jobs to fund my first degree. I was interviewed by the four largest state-owned companies of the time. I felt that as a citizen of my country I had the God-given right to be employed added to that in my own mind I knew everything. There was nothing that anyone could teach me.

Best Practices in Dental Office Scheduling
When looking at the best practices for how to arrange your schedule in a dental office, I want to start with an exercise that Stephen Covey did years ago. He filled a jar with rocks and then asked if the jar was full - some naturally said "yes". Then he added small pebbles to the jar and they fell down in the cracks and filled some additional space. He then asked if the jar was full - some said "yes". He then added sand, which fell down in the cracks and filled the empty spaces and then asked yet again if it is full. Some again said "yes". He then added water to the jar, which of course filled the extra spaces, to which he now agreed "now it's full".
If, on the other hand, you were to fill the jar with sand first and then ask the audience if it was full of course all would say "yes". With this scenario in mind, he then posed the question of, "now could you add any rocks to this jar?" The obvious answer was "no". You have no left over space to put anything into the jar.
