If you want to change the visible, you must first change the invisible
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 re-sults) and we don't like them; there 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's 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 change the roots. If you want to change the visible, you must first change the invisible.
Focus is saying no to 1,000 good ideas.
Every time I read a management or self-help book, I find myself saying, “That’s fine, but that wasn’t really the hard thing about the situation.” The hard thing isn’t setting a big, hairy, audacious goal. The hard thing is laying people off when you miss the big goal. The hard thing isn’t hiring great people. The hard thing is when those “great people” develop a sense of entitlement and start demanding unreasonable things. The hard thing isn’t setting up an organizational chart. The hard thing is getting people to communicate within the organization that you just designed. The hard thing isn’t dreaming big. The hard thing is waking up in the middle of the night in a cold sweat when the dream turns into a nightmare.
