A new leadership tool is at hand this week. It’s summertime.

Despite the demands of this challenging economy, things are just different. There’s less traffic on the road in the mornings. Less people in the office because of vacations. Everyone knows you have to get major deals closed by mid-July because key decision-makers will be hard to assemble until after Labor Day. Inevitably there’s more recreation and leisure in your schedule.

All this presents Leaders with opportunities to “shift with the season” — to experiment, create, learn, reboot. And when Labor Day gets here (80 days and counting), you can decide to stop or continue. Will you take advantage of it?

How do these affect your thinking first thing in the morning . . . as you head in to lead your company?

“As a man thinketh in his heart, so is he.” — Jewish Proverb

Leaders must be intentional about their thought life. Everything they DO is traceable to how they THINK.
