Today begins Teacher Appreciation Week 2012, and that means honoring your teachers with a special gift or some other token of appreciation.

We have much to thank our teachers for, whether it be inspiring us to choose a certain career path or changing the way we think about the world.

Teachers have long been recognized for how they shape young minds, stretching as far back as ancient Greece.

Those who educate children well are more to be honored than parents, for these only gave life, those the art of living well, the ancient Greek philosopher Aristotle once said.

Former CBS news anchor Dan Rather likened teachers to guides that help us overcome obstacles so we can achieve our goals.

The dream begins with a teacher who believes in you, who tugs and pushes and leads you to the next plateau, sometimes poking you with a sharp stick called truth, Rather said about teachers.

Some say teachers are unpaid fairly given the huge responsibility they have with young children, who are the leaders of tomorrow. According to payscale.com, the median salary for teachers in the United States is around $40,000.

Modern cynics and skeptics see no harm in paying those to whom they entrust the minds of their children a smaller wage than is paid to those to whom they entrust the care of their plumbing, President John F. Kennedy once said.

Teacher Appreciation Week 2012 runs from May 7 to May 11.
