You train your brain by your self-talk style: positively or negatively. It is important do use positive words because your words are converted into pictures that the subconscious can follow, since it doesn’t use language, per se. If you say, “Don’t touch the stove,” a picture of touching the stove pops up, and the brain may follow that picture. “Keep your hand away from the stove” is more likely to get the desired result “Remember your homework,” is more effective than “Don’t forget your homework.” You’ve no doubt heard on TV or billboards, “Don’t forget to vote.” “Remember to vote,” would likely be much more effective. Estimates are that most people grew up hearing 7-10 negative comments or instructions for every positive. People’s brains are filled with negative-comment tapes. No wonder people keep repeating old negative patterns of behavior. The subconscious doesn’t seem to understand the word “no,” either. It wants a yes! So, use “yes” plus a qualifier. “Yes, you may have a healthier cookie after you finish lunch.” Just keep repeating that as many times as you need to for the brain to “get it” and stop asking for a sugary treat right now.
