Don't let

Don't let anyone get you down
Don't let anyone take away your smile
Don't let anyone take away your joy
Don't let anyone interfere with your happiness
Your misery will be the happiness of others, and your happiness will be the misery of those who are jealous of your.
Don't be sad for people who don't deserve. The best thing to do is live your lives and ignore those who don't deserve even a bit of your attention. Being happy and ignore it the best we can to hit these people.
