Five ways to be stay happy:
1) Don't expect perfection out of life. Stuff will happen, so just be ready for it to come.

2) Don't judge others, because it makes things harder than they need to be.
Be able to accept others differences.

3) Be grateful for what you have. Everyone has something to be grateful, so just be able to think over what it is you have.

4) Be in control of your life. Don't let peoples opinions decide what it is you do. Make your own decisions for yourself.

5) Work for what you want. Stop looking at everything you don't want to have or to happen and focus on you do want.
