Meaning of The best way to cheer yourself up is to try to cheer somebody else up. Quote by Mark Twain.
The formula of happiness and success is just, being actually yourself, in the most vivid possible way you can.
Be happy for no reason, like a child. If you are happy for a reason, you’re in trouble, because that reason can be taken from you.
You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.
If you do build a great experience, customers tell each other about that. Word of mouth is very powerful.
