In Seth Godin's latest book, Linchpin, he describes the lizard brain and how it is seeking the simple path in life. "The lizard brain is hungry, scared, angry, and horny...and only wants to eat and be safe." And while this reptilian side of our brain will cause us to fight when necessary, it may also keep us from reaching out beyond our comfort levels.
The lizard brain wants you to order in versus venturing out to a new restaurant. It would rather you watch a movie you've already seen (possibly several times) instead of seeing a new movie or a touring play. The lizard brain may also be what's keeping you from trying something different to overcome your pain. It would rather have you sit on the couch and live with physical limitations and less activity than get out and play.
Your lizard brain says, "Oh, I've already tried everything." This statement give security and certainty in only one thing -- that you don't have to try any more. The unintended consequences, however, are devastating and include loss of desire & motivation, lack of creativity, depression, and hopelessness.
Another comment the lizard brain makes is, "I would, but it costs too much." As with the last comment, this will lead to safety & security, and create a scarcity mindset that things-are-only-getting-worse. Investing in yourself is not a lizard-brained idea because it would cause you to think ahead... think of the success, achievement and hope of actually getting better, enjoying a lifestyle you once had.
"It's too far, too complicated, takes too much time, too hard, too much effort, etc., etc." Your lizard brain will go on and on about how much you'd rather live with the pain, succumb to a less-than-optimal lifestyle, or simply wait for an act of divinity, before coming out of the safety zone. After all, drugs are cheap, surgery may be covered by insurance, and I need to save all the energy I have left! And while these comments may be justifiable, the truth is that you have more in you.
You have a gift, a birthright, to being pain free. Conquer the lizard and get back your higher functioning self. You'll thank yourself that you did, and so will those around you who've been living with the lizard.
