Before I say this, I am not referring to some sort of new age aura or anything like that, but rather using our nervous and pent-up energy for good things, instead of just being nervous or aimless, etc.
I have been reading some books on public speaking recently (maybe more on this later), and they give some tips on how to take excess energy (much of which could be nervous or undirected) and focus the energy to something positive, namely the current intellectual, spiritual, or athletic performance. One idea some authors recommend is to focus on something positive, e.g. a happy moment or person. This is based on research that people are literally physically stronger when they think of something positive than when they think of something negative. I tend to think of two things to channel my energy to increase my performance: the photo of my niece grace smiling and running outside on a hot summer day. Today, while I was running (inside), I noticed that not only did I feel a burst of energy when thinking of niece, but I always smiled at the thought of her smiling in that photo. Another technique I have read about is to make yourself taller, which means standing proud to exude confidence. I tried this today, and I did it by pretending that my head and shoulders were attached to a string hanging from something very high in the air…it was actually quite easy to do when I was imagining that. Again, I felt an improvement in my energy levels. I am experimenting with ways of my own, and will let you know about these in the future.
