William BridgesMuch as we may wish to make a new beginning, some part of us resists doing so as though we were making the first step toward disaster.
William BridgesChange is situational. Transition, on the other hand, is psychological. It is not those events, but rather the inner reorientation or self-redefinition that you have to go through in order to incorporate any of those changes into your life. Without a transition, a change is just a rearrangement of the furniture. Unless transition happens, the change won't work, because it doesn't 'take'.
