If you want to change the visible, you must first change the invisible

Excerpt from Secrets of the Millionaire Mind by T. Harv Eker:

"Imagine a tree. Let's suppose this tree represents the tree of life. On this tree there are fruits. In life, our fruits are called our results. So we look at the fruits (our results) and we don't like them; they aren't enough of them, they're too small, or they don't taste good.

So what do we tend to do? Most of us put even more attention and focus on the fruits, our results. But what is it that actually creates those particular fruits>? It's the seeds and the roots that create those fruits.

It's what under the ground that creates what's above the ground. It's what's invisible that creates what's visible. So what does that mean? It means that if you want to change the fruits, you will first have to changed the roots. If you want to change the visible, you must first change the invisible."

Although I have not been thinking of becoming a millionaire, I am just looking for comfortable simple life (I do not know if it requires million of dollar :p ) . But I think, words above applied to all human beings in all situation, no only in terms of money, but also personality and attitude.
