If you do not succeed, you will be worried. Try to control this sense of dejection and elation. Become truly wise. Do not allow yourself to be subjected to these wavering feelings of elation and dejection. There is no human being who is not engaged in actions.
Every person has a human body for the express purpose of performing actions.
To sanctify the body, you have to perform only good actions. For every action there will be a fruit. You should realize that the joy which you get in performing an action is much greater than the joy you get from the fruit of the action. For example, on an auspicious religious festival, a family may choose to be together throughout the night with other devotees, relatives and friends to sing devotional songs. As long as they are engaged in their practice and involved in their ceremonies they are unaware of any feeling of fatigue.
