So I've got this new thing now where I aim to compliment 5 random people a day:)
It feels really great, and not only makes them happy but makes you feel good too! Really simple things like " I love your nail varnish" or " Your top is soo nice" work so well to bring smiles to people's faces :)
Of course, the comments have to be real, because a lot of people can tell when it's fake!

Try it :)
