I've been recently coaching someone and reminding myself that lives and careers have different stages, and these stages require different strategies.<p>When you're on the younger side, a lot of your "win" comes from avoiding obvious mistakes. As in, "do homework" rather than "get high" or "pick a job where you will learn more" vs "coast."<p>As you grow successful, you are no longer picking between smart and dumb, options, but rather between two good ones. This is harder. You have to get good at saying NO to good opportunities and let real problems fester, so that you can focus on the <i>even more</i> important stuff. That's the mode in which you need the Eisenhower matrix approach - to force yourself to figure out what you will say YES to and thus what you will have to feel good saying NO to.
