Real wisdom is simple. Living life rightly does not have to be a complicated challenge.
It's not the matter you cover so much as it is the manner in which you cover it.
What you become directly influences what you get.
The best motivation is self-motivation.
The good life is not an amount; it's an attitude, an act, an idea, a discovery, a search.
Work harder on yourself than you do on your job. If you work hard on your job, you can make a living. If you work hard on yourself, you can make a fortune... Income seldom exceeds personal development.
