Do you do things with an expectation?I recently attended a stress management course for about one hour. In that they said, one of the reasons for stress is we expect returns for our deeds. We do good to someone and we expect them to thank us or at least be grateful to us. We feel sad when they did not thank us. But why do we expect it? People might not live up to our expectations and we can't change them. The only thing we can change is our thinking, expectations etc.
We will definitely be rewarded for our good deeds, but may not be from the same person to whom we have done a favor. So, don't expect anything from them. They might reward you or else, someone else in the world will give you the reward. Almighty is watching us and he knows and does count on the good things we do, hence he will make sure that our good deeds are rewarded. A life without expectations itself can increase our happiness.
