Be Happy! Do Your Duty Happily without Attachment to its Results

To be happy one should do one’s duty without attachment to its results. In Gita Lord Krishna teaches this philosophy of Nismam Karm to Arjun. If we are not too anxious about the success or failure of our efforts but are interested in only doing our duty to the best of our ability, we do not become unhappy when the results are not as expected. Doing our duty is under our powers not its results.
