We can increase our joy anytime by taking some pain to help someone who is less fortunate than us. Kindness is also a seed for joy. Joy cannot be bought from a super market but can only be received in spirit from God; when we try to put God's word into practice by releasing that act of kindness in fulfilling God's command saying; love your neighbor, as yourself. So be: kind, nice and good; someday we will have to leave everyone and everything behind for someone. So try to put a smile on someone's face every now and then thereby making God feel proud of you and increasing your joy within you.
