While we're on the subject...

When I was a police officer, we had a little saying that went "you can never have enough training..."
Same applies to whatever you do.It's not just time for kids to go back to school. I am attending a staffing seminar next month to learn better ways of hiring and staffing my sites. I look forward to it because that will help me to grow and go after more business.
If you want to stay on top of your profession, you must constantly be learning. Whether it's academically or on new methods or technology. The Internet, your local Chamber of Commerce or business partners are good places to start looking where you can find classes,etc. to improve your skills.
Plus it shows that you think enough of yourself and your profession to stay informed. Change is inevitable. Roll with it...
