I appreciate the fact that injuries in sport did not crush Lakshmi's spirit, and that she chose to see the positive in her adversity and move to other fulfilling careers instead of wallowing in negativity and depression which is counter-productive.
Indeed, if one has a positive attitude, one will be able to bounce back from adversity and move to better states and circumstances. A negative attitude on the other hand, will only lead to a more negative state.
To create and maintain such a positive attitude, especially during adversity, is hard, but that is what spiritual and mental strength is all about.
A teaching by Swami Vivekananda on a positive mental attitude...
It is our own mental attitude, which makes the world what it is for us. Our thoughts make things beautiful, our thoughts make things ugly. The whole world is in our own minds. Learn to see things in the proper light. -- Swami Vivekananda
