Purpose without priority is powerless. - Gary W. Keller

Since there is always another level to learn, mastery actually means you’re a master of what you know and an apprentice of what you don’t. In other words, we become masters of what is behind us and apprentices for what is ahead. This is why mastery is a journey.

Think as big as you possibly can and base what you do, how you do it, and who you do it with on succeeding at that level. It just might take you more than your lifetime to run into the walls of a box this big.

Being needed is incredibly satisfying, and helping others can be deeply fulfilling. Focusing on our own goals to the exclusion of others, especially the causes and the people we value the most, can feel downright selfish and self-centered. But it doesn’t have to. Master marketer Seth Godin says, “You can say no with respect, you can say no promptly, and you can say no with a lead to someone who might say yes. But just saying yes because you can’t bear the short-term pain of saying no is not going to help you do the work.” Godin gets it. You can keep your yes and say no in a way that works for you and for others.
