The truth is that if you're a people-pleaser, you've been using the people in your life to compensate for something that's been missing within you; you've been focused on getting others to meet a need, rather than on creating real connections. This might explain why you're not as happy as you could be, today.
You can always be fired, downsized, or replaced. Your company could fold. The economy could tank. Depressing, I know. But, oddly enough, it's also empowering. Knowing there's no 100% guarantee frees you from pressure fall in line, fly under the radar, cave to the pressure, and suck it up, all for the sake of "security."
Today's topsy-turvy world has us all running madly in every direction. We often feel overwhelmed with what's before us -- and that is, even, before our feet hit the floor in the morning. We are losing our joie de vivre; there is precious little fun and almost non-existent downtime in our lives today.
