“It’s simple but really, really hard. Let’s look at some of these side effects. You’re going to feel uncertain; I guarantee it. “Should I really give this up? Is this the right thing to do?” Giving up a value you’ve depended on for years is going to feel disorienting, as if you don’t really know right from wrong anymore. This is hard, but it’s normal. Next, you’ll feel like a failure. You’ve spent half your life measuring yourself by that old value, so when you change your priorities, change your metrics, and stop behaving in the same way, you’ll fail to meet that old, trusted metric and thus immediately feel like some sort of fraud or nobody. This is also normal and also uncomfortable.”
