Frequently, erroneous thoughts and illusions enter a person's mind and disturb his concentration. When you lack peace of mind, you will not be able to study Torah or pray properly. The best advice is to develop the following attitude:

"Want that which your Creator wants for you. Take pleasure in what you have, whether comparatively little or a lot."

Once you adopt this attitude, you will be able to find peace of mind and this will be therapeutic for both your body and soul. You will be able to find success - whatever the particular circumstances and challenges you find yourself in.
