Want --along with why, try, need, but, never and because – each contain some kind of an energetic limitation. “Want” primarily means and has the energy of “lack”.
So when you say “I want money” you are actually saying “I lack money,” which reinforces both your point of view and your reality of not having money.
If what you'd actually like is more money, then instead ask a question, for example “What will it take for more money to show up in my life?” Questions will always help you see how you can create the change you're looking for.
So every time you catch yourself in the act of saying want (you can also add why, try, need, but, never, and because to the list of words to leave behind) stop, smile, ask “What question could I ask here instead, that would help me create what I'd really like?”
