The West is symbolized by journeys taken and goals reached in Native American imagery. The sun sets in the west, completing the journey of a day. So I see this direction meaning action. No journey can be taken or goal reached, without taking action. And taking action means putting your best foot forward.
Life is an action word.
Everything you've heard me say today is just an idea, until you put it into action. Action is the forerunner to success. Actions which, when applied to a goal, are always successful. And having one, two, or even a track record of successes under one's belt leads to bolstered self-esteem. And action is the forerunner to success.
