Compliments
Never be tight-****** in dispensing them, for as trivial as they seem, they could mean a world of difference to the other person
It could save that waiter from quitting his job
It could save that homeless man from becoming a criminal element
It could save that relationship from the brink of falling apart
Never be selfish in handing compliments, for you lose nothing
Because there will be days where you're going to need it
Because one day, it will make a difference in your life—one day, it will save you
