If there is suffering, then it's best to accept it, because it won't go away just because you pretend it's not there. If there is joy, then it's best to accept that too, even though you're afraid it might end one day.
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.
From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
Joy and growth come from following our deepest impulses, however foolish they may seem to some, or dangerous, and even though the apparent outcome may be defeat.
