As we go into Shabbat once again, it's important to place our lives in perspective. What we have, not what we lack. It is easy to focus on our lack of money, friends, health, - the list goes on. Sometimes all we need is a small reminder of what is good in life to return to an attitude of thankfulness. For me, simply teaching a class of students eager to learn, on a subject I love, brings me back to the good in life.
