Feel pleased that it is there, and remind yourself often of the added sense of security that it brings to you.
Now, as you move through your day, take note of the many things you could purchase with that $100: As you pass a nice restaurant notice that, if you really wanted to, you could stop in and have a delicious meal. As you see something in a department store, remind yourself that, if you really wanted to, you could purchase that because you have $100 in your wallet.
By holding the $100 bill and not spending it right away, you receive the vibrational advantage of it every time you even think about it. In other words, if you were to remember your $100 and spend it on the first thing that you notice, you would receive the benefit of really feeling your financial well-being only once. But if you mentally spent that $100 20 or 30 times in that day, you would have received the vibrational feeling advantage of having spent 2 or 3 thousand dollars.
Each time you acknowledge you have the power, right there in your wallet, to purchase this or that, over and over again you add to your sense of financial well being so your point of attraction begins to shift.
