There's an easier concept to grasp and one that's more powerful.
That's simply being "better."
Whatever you do, you'll never be perfect. So, striving for perfection is a lost cause. But, trying to be better gives you all kinds of options and opportunities. You can strive to be better than you were last year, last month or last week.
Better is a relative term, of course, so you need to come up with ways to measure your progress. Is it more sales, more contacts, more content, better content, fewer meetings? You'll never be sorry by striving to improve your performance, one day at a time.
