September 1st will mark the unofficial end to the summer. Seems like it only started. Some may think that one's learning stops at the end of the school year when in reality we learn something every day.
There's the formal education of school, then there's the informal education life teaches us. Did we learn something about ourselves? Was there any improvement of a particular talent or gift? Did you have an epiphany about something that may have been spoken or performed a while back? Either way we are not the people we were several weeks back.
As a the new school year begins, see if you can apply some lessons you learned during the warm summer months. It may prove invaluable in the future. Nothing that you learn ever goes for naught.
