Recently, I have experienced the power of mental override to physical obstacles. The two examples that bring me to my conclusion of this ability are as follows.
In May I began working a new day job. When I left work for the day, it was rather warm out. Some early summer temperatures. When I got in my car it was oven-like, but not intolerable by standard human.
For most of my life, I have found that I was very quite intolerant to the summer heat. Any jobs involving hot kitchens or working outside in warm weather I immediately cross off the list as possible modes of employment. I do this from past experiences.
Well that day when I got into my car, I stopped myself before turning on the air conditioning. I relaxed myself, focused on tolerating the heat, and just told myself the following things: This is comfortable. This feels good. I like the heat. I prefer the heat. This is enjoyable. Etc.
Since then, I have enjoyed a very comfortable and non-heat-inhibitive summertime. I was from that point able to embrace the heat and feel comfortable in it.
The second example is from today actually. Before today I have been very on and off about exercise. I try to keep to a simple daily exercise regimen, but it typically goes weeks on, months off, weeks on, etc.
Well, in the week before an upcoming convention, I decided to take back up this regimen until at least then. And so, typically I do maybe three sets of 20-30 push ups as one of my exercises. Today I took the mental override approach and applied the same type of self talk as before. I told myself before, during, and after pushups that: I love push ups. Push ups are the greatest. They feel amazing. There is nothing I'd rather be doing. Push ups are my favorite. Etc.
Today I cranked out a total of 100 push ups over a few sets.
In light of this, I am now going to apply this mental override in other things I may be lazy or anxious about. I would recommend that everyone try this technique of overcoming whatever. It's worth a try and will possible overhaul you willpower.
