You can make massive positive changes in your life -- such as taking actions you were afraid to take and ridding yourself of such negative feelings as anxiety and anger -- by eliminating your limiting beliefs.
At that point I realized that beliefs weren't the only cause of our feelings and that stimuli could be conditioned to cause emotions, such as being told what to do causing anger and not living up to expectations causing anxiety.
In order for anything to exist, it must be distinguished from everything else. If no distinction is made between a specific thing and everything else, then there is only an undifferentiated everything -- which is another way of saying nothing.
The meaning you give to what happens to you totally determines your reaction to what happens to you. One meaning can lead to suffering; another meaning of the same event can lead to excitement and happiness.
Eliminating the relevant beliefs definitely will change your behavior and feelings. But having wealth involves much more than beliefs, although getting rid of crippling money beliefs is certainly a precondition.
