The universe is working for you. Thank the universe. Don't forget to thank.
Gratitude is for 2 types of people - those who help us, and those who give a gift to us.
When someone helps you, don't take his help for granted. Show your gratitude towards his help. Say it with a message, or with words, or with a smile, or with a small token of a gift. Don't forget to thank.
When someone gives a gift to us, be sensitive towards his love for you. A gift is a token of love. Every gift has the stamp of love from the giver. Appreciate the gift, and express the love back. Thank the person. Don't forget to thank.
