1. Consider that in order to build character the practice of patience is essential.
2. See that the best way to practice patience requires an enemy.
3. Understand that in this way enemies are very valuable for the opportunities they provide.
4. Decide that instead of getting angry with those who block your wishes, you will inwardly respond with gratitude.
By seeing things this way you will change your attitude toward adversity. This is very difficult but very rewarding. For only when faced with the work of adversity can we discover real inner strength.
