Don't forget to smile today, it may be your smile might be the one thing someone going through a tough time needed on that day.
Don't forget to lend your hand, hold the door, speak a kind word, if you do it enough, it's second nature and perhaps the next person next to you might too.
Don't forget to be a little kinder than you feel, you never walked in someone else's shoes and it's hard to forgive but easier to choose some peace in your mind.
Don't forget there is more good than evil in this world, and doing the right thing takes a lot more courage than responding in hate.
