Our brain is like a thermostat. It will always work the way it is planned & programmed. For example, if the air conditioner is set to 25 degrees, and the room temperature is higher than that, it will allow all cooling devices focus their energy on cooling the room. But when the room temperature is 25 degrees, the thermostat will command all air conditioner to stop cooling.
Our brain works the same way. If we believe that we are middle class people, or that we can make a living by doing normal work, our mind will be certain that this is possible. The mind always brings us what we believe. Therefore, in this case it will ensure that we can live a normal life with our pay check.
But, if it happens, a person earns more money in a good business or lottery, or by inheritance, our mind will also give us what we believe. We will lose money, spend it, gamble, share it or spend it until we get back to the point where we are living on a pay check again. It works exactly like a thermostat: it saves you extra money coming to us after you reach the limit we set. These things have been proven by practice several times. The most common are those who managed to save their money after winning the lottery. People often start to do strange things for money, to give away gifts, to buy expensive gifts, to gamble, or to do other things that will cause them to lose more money.
That is why we need to change our ways of thinking, change our beliefs in order to be successful. The thermostat needs to be reset. It should be set to unlimited temperature. One has to be a millionaire mentally and then in real life. If we want to lose weight, we need to lose weight first mentally, so that we can get smaller and more realistic. If we want to cure the disease, we must see ourselves as healthy. If we want to meet the right partner, we need to envision him/her first and make the happiness that comes from meeting him/her alive. But remember, imagine everything as it is happening now.
The brain can be programmed to achieve the desired results in the future, only the brain must change and the rest will be cared for by the brain itself.
