Attitude is the summation of our beliefs to a particular phenomena.If we believe that it is not needed or dangerous to step out of our limits, we will forever be averse to risk-taking.If we also believe the decisions of superiors must never be questioned ( Being obedient) then our work attitude will be of a person who will do what he is told and no more. An extremely conservative, safe yet dull sort of person.
So to change our attitude, first observe our reactions to stimuli around us.
Keep making notes.. especially of instances when we inexplicably feel angry or tense or happy.
especially when we suddenly dislike or like someone.
Those are pointers to our unconscious beliefs.
Interestingly when we become aware of a belief, it instantly changes!
So we become more and more aware of our beliefs we will be changing more and more of them. And suddenly we realize that our attitude to a particular phenomena has changed.One another clue is to know that our beliefs are changing is when we find that we are getting different results to the same phenomena.
That is if you change your belief of money from lack to plenty, suddenly you will find money appearing in your life.If you change all your beliefs about money ( oh, there are so many!) your attitude to wealth will change and that will bring in fundamental changes in your life.
