Quotes on Never Stop Improving

I don't know the rules of grammar... If you're trying to persuade people to do something, or buy something, it seems to me you should use their language, the language they use every day, the language in which they think. We try to write in the vernacular.

Life is about balance. Be kind, but don’t let people abuse you. Trust, but don’t be deceived. Be content, but never stop improving yourself.
