I believe that dreamers who simply imagine things that would be nice but are not possible don’t sufficiently appreciate the laws of the universe to understand the true implications of their desires, much less how to achieve them.

People who excel at book learning tend to call up from memory what they have learned in order to follow stored instructions. Others who are better at internalized learning use the thoughts that flow from their subconscious. The experienced skier doesn't recite instructions on how to ski and then execute them; rather, he does it well "without thinking," in the same way he breathes without thinking. Understanding these differences is essential.

Don't worry about looking good - worry about achieving your goals.

To have an idea meritocracy, one needs to do three things. First, they have to put their honest thoughts on the table, for everyone to look at and everyone to work through. Second, they need to have thoughtful disagreement, by which there are quality exchanges, in which there's open mindedness and the realization that no one has all the right answers. And you can work through that and get to better answers because good collective decision making is better than any individual decision making. And third, you have to have ways of getting past the disagreements if they remain.

Never say anything about a person you wouldn't say to them directly, and don't try people without accusing them to their face. Badmouthing people behind their backs shows a serious lack of integrity and is counterproductive. It doesn't yield any beneficial change, and it subverts both the people you are badmouthing and the environment as a whole.
