Be wise and don't let good things crowd out those that are essential.
So many people spend so much time on things that aren't important. It's the difference between success and failure.

You know in a startup, you only need three people. You need someone who can make something. You need someone who can sell it. And you need someone to collect the money. That's the only three roles in a startup. So which one are you?
What are the critical success factors of your job? What must you be absolutely, positively excellent at doing to be successful?
What is the most important thing you could be working on in the world right now? ... And if you're not working on that, why aren't you?

Your most important tasks and priorities are those that can have the most serious consequences, positive or negative, on your life or work. Focus on these above all.
