This is a term that I have just come across again. In essence it says that if you re-enforce any action (or thought) it will become ingrained. It makes me think of the idea that Earl Nightingale developed all those years ago. “We become what we think about”.
Other similar sorts of homilies are: what you focus on grows in importance and fact, you reap what you sow and so on. In other words, what you are focusing on is very important. It sets you up for more of whatever you are focusing on.
Note: it does not work in the negative. The human brain does not process negatives. A negative is a concept that our brain just does not deal with. If you tell yourself not to think of a pink elephant, guess what the first thing to come into the mind is. Yep, there is that pink elephant. In other words, if you try to focus on not having or doing something, you will actually be reinforcing the exact opposite. You will get more of what you do not want.
As we know, life is all about choices. Choose carefully what you choose to focus on. It is perfectly fine to think about a problem but we must be careful not to focus on the problem and how terrible the effects are on us. Rather, identify the problem, think briefly about the terrible consequences, and then move ahead to what outcome you really want. If you have financial troubles, shift the focus onto having sufficient funds. If you have poor health, shift the focus to better health and feeling happy anyway. If you are sad about a happening in your life, shift the focus to how you can find things to be grateful for and be happy again.
There is a sort of gyro-scope in your brain that will work hard to notice opportunities to fulfill your goals and re-enforce whatever it is that you are focused on. Focus on what you want more of. Your brain will point out opportunities that you might have otherwise missed. When you see those opportunities, act on them right away. Remember the law of re-enforcement. If you do not act, you are re-enforcing the behaviour of seeing opportunities and taking no action. Eventually, you will not even see any opportunities and you will convince yourself that you really cannot change anything in your life. Take action!
