Simplicity

Simplicity means different to many people, contentment is the core to simplicity. It's all about being contented with simpler things, being satisfied with less, rather than always wanting more, acquiring more and never be contented.
Simplicity means examining why you want more, and solving that issue at its root. At the root of wanting more is not being content with what you have. Once you’ve learned to be content, you don’t need more. You can stop acquiring, and start enjoying.

Saying is easy, but how to get there? If getting there is easy, then why do sadness exist?

One
Count your blessings.

Two
Stop, and remind yourself.

Three
Stop, and consider why you want something.

Four
Take time to appreciate your life.

Five
Show people you appreciate them.

Six
Breathe, and smile.

Last and the most important
Learn to enjoy the simple things.

Who seeks more than he needs, hinders himself from enjoying what he has. Seek what you need and give up what you need not. For in giving up what you don’t need, you’ll learn what you really do need.
