If we can manage to refrain from harming others in our everyday actions and words, we can start to give more serious attention to actively doing good, and this can be a source of great joy and inner confidence. We can benefit others through our actions by being warm and generous toward them, by being charitable, and by helping those in need.
It's always necessary to know when a stage of one's life has ended. If you stubbornly cling to it after the need has passed, you lose the joy and meaning of the rest. And you risk being shaken to your senses by God.
What can become of him if he is in such bondage to the habit of satisfying the innumerable desires he has created for himself? He is isolated, and what concern has he with the rest of humanity? They have succeeded in accumulating a greater mass of objects, but the joy in the world has grown less.
Things in which we do not take joy are either a burden upon our minds to be got rid of at any cost; or they are useful, and therefore in temporary and partial relation to us, becoming burdensome when their utility is lost; or they are like wandering vagabonds, loitering for a moment on the outskirts of our recognition, and then passing on. A thing is only completely our own when it is a thing of joy to us.
There is, of course, no joy so great as the cessation of pain; in fact all joy, active or passive, is the cessation of some pain, since it must be the satisfaction of a longing, even perhaps an unconscious longing.
Keep the commandments of God. If you have sinned, the sooner you begin to make your way back, the sooner you will find the sweet peace and joy that come with the miracle of forgiveness. Happiness comes from living the way the Lord wants you to live and from service to God and others.
