How about intentionally doing something nice for someone random, it could be helping someone with the door, with their bags, or even making someone's day with a compliment.
Do something nice for your family..which I'm sure you already do- that part should be easy!
And lastly do something nice for yourself today, take some time to yourself to take a longer bath, or treat yourself to a sweet treat, whatever it may be! ;)
Hope you enjoy a wonderful weekend, "celebrating" Do Something Nice Day, is a great way to start off the weekend right!
