All change really works from the inside out. It starts with the statement I need to change not circumstances. Without this kind of emphatic ownership we will tend to look for or wait for external events that may or may not occur and are not within our control.
If what we have been doing is not getting what we want then we need to change our actions. Our actions will not change until we change how we feel about what we are currently doing.
To look outside of ourselves keeping the same perspective and attitude that have been unsuccessful to date is pointless. Granted we have to ensure that we have spent enough time using our current approach to have seen any results from our efforts.
To change how we do things requires a new perspective in order to discover new approaches. Thus change occurs from the inside out.
