"Keep up the good work!" is an easy and encouraging message to say.

These five words can be tremendously valuable. It's easy to think that when someone successfully does positive things, he will be aware of it and doesn't need to hear this expression of recognition. But at all stages of life we need encouragement.

When we are just starting out, we usually need positive feedback from others to know that we are doing well. This feedback is especially valuable when the encouragement comes from our parents, teachers, mentors, employers, coaches, and anyone else we hold in high esteem.
