We create our own reality. We attract those things in our life (money, relationships, employment) that we focus on. I wish I could tell you that it is as simple as stating an affirmation, but no affirmation is going to work if your thoughts or feelings are negating the positive. When we focus on "having less" then we create that experience for ourselves. When we focus on "I hate my job" then we will never notice the aspects of our employment that might be satisfying. Basically, just wanting something isn't going to bring that to us when we continue to obsess on the not having of that something. All we will experience is "not having" and will be ultimately blocking our true desires. Better to focus on a particular object or scenario rather than on winnings or cash. Another mistake that we make is that we tend to think of abundance in terms of how much money we have in our bank accounts. I personally think focusing on winning the lottery is a fruitless event. Focusing on winning the lottery is kind of like focusing on "not having." I say this because of some discussions I've had with those who have held this desire, they have shared what they would do with the winnings if they won. Yet, some of the things they say they would do with the money they could actually already be doing with their current incomes on a smaller scale, but they don't. Why not? They cling to what they perceive as their "meager savings" with the attitude that they don't have enough out of fear.
Here is an example of this:
A man's sister owns a car that is need of repair. The brother says "If I won the lottery I would buy my sister a new car." But actually, the brother has the means to take her car to the mechanics and pay out $400 needed in repairs to assure that his sister has a dependable car to drive back and forth to the market. When asked why he doesn't then just go ahead and have her current car repaired, he answers, "Well gee, I only have $800 in the bank, and doing that would knock out half my savings. What happens if my car needs repairs next week or my daughter gets sick and needs to see a doctor?" So you see the person's true focus is on "not enough" rather than being focused on winning the lottery. When we are focused on "not enough" it won't ever matter how much money we have, it will never be enough. Suggesting that he pay for his sister's car repairs brought his fears out into the open. It would be nice if the fellow could trust that by helping his sister and paying for the repairs he would not put himself at financial risk. But for the time being, while he feels he must hold onto that fear reality, I would suggest this man focus on visualizing his sister driving safely to and from the market in comfort and without experiencing any mechanical breakdowns. This would be a positive image/thought to get that picture to become a reality. Another suggestion would be to introduce the Law of Attraction to his sister so she can start attracting a new car for herself among other things she might desire.
The Law of Attraction says that "Like Attracts Like" meaning that your thoughts send of energy waves or vibrations into the Universe, thoughts of similar vibrations will draw to one another. So if you're thinking wonderful thoughts of a beautiful rainbow or a magnificent painting your vibrations will match your thoughts and draw things of similar vibrations to manifest allowing you to continue feeling wonderful. The same is exactly true if the thoughts are negative, the Law of Attractions pays no attention to whether the thoughts are positive or negative. It responds to whatever your dominant thought is focused on and says "Your wish is my command". Most people focus on lack, worry, doubt, fear and wonder why their life continues this way.
I'll tell you, the Universe is like a projector and whatever you reel you give it, it's going to play it on the big screen we call our Life Experience. If you are aware of this fact then you will begin to recognize a negative thought and can immediately change it, if your start feeling fear think courage. When you start having the thought of lack think thoughts of abundance, when you start thinking thoughts of sickness think thoughts of great health. Immediately your mood will change and you'll be grateful and happy and the Universe will manifest more things and people to create more of these grateful and happy feelings. The fastest way to manifest your thoughts and desire is to have gratitude for what you have now and what you desire knowing without a doubt that it will manifest. Many people go through life coasting and missing out on the beautiful experiences this life has to offer. When you live a life of Gratitude and Love your thoughts are always of peace, prosperity, abundance, beauty. This is your true "Self" that has been yearning for expression all of your life, it causes the disease and sickness in most people because their spirit's longing for expression is held back and ignored, and inside, the feeling of lack takes effect on the body. This is the day that you decide if you desire to drift along or create your way to achieve wonderful things, whatever makes you happy without denying another of the same happiness.
Think good thoughts as William Shakespeare stated "To Thy own Self be true".
