Since this is the first suggestion, I will make it a rather easy one to accomplish.
Today, I suggest that you send a message to someone telling them a reason why you think they are great. Thank them for something they have done for you recently, or just thank them for being a wonderful friend, mother, sister, or just for being a great human being. Tell them something truthful that will make them smile, even if it’s a simple “Have I told you lately what an amazing friend you are?”
Put a smile on the face of someone who deserves it today! It can be in a facebook message, an email, a text, a letter, a phone call, or in person.
I would love to hear your own suggestions for acts of kindness!
