I read this the other day and had to share.
"The secret of happiness is to make others believe they are the cause of it."
Not sure who or what it's from, but what an astounding truth! And trust me- I don't want to change this person's words of wisdom, but if I could, I would say "to let others know they are the cause of it." Either is fine.....but letting someone know they are the cause of your happiness is what you have to actually do. Put some lovingkindness into your relationships (or add to it!). Think about how much you appreciate someone, let them know! They will believe it!!!
Let someone know how happy you are to have them in your life. Not only that, make them believe it! :-)
