Dear WASD,
Everytime I have a lot of energy on me, usually an impulse to do something such as going for a walk or wanking it off will try to steal the energy from me.
Resisting the temptations is the only way.
The more energy you hold, the more you must focus in order to sustain it otherwise you fall prey to magnetic equilibrium. Either you go against the stream or you swim with it.
The higher you go, seperating yourself from the standard, the deeper is the abyss you can fall.
I disagree with a couple of things here: First, taking a walk. I find it can be great for building energy, especially in nature. I love going outdoors when I'm highly energetic, and in fact, keeps me balanced. And making exercise a pattern in you life in GREAT for energy building. Wanking it... I don't know, I guess it depends on how much energy you put into it.

2nd, I don't think it takes more focus to hold or store more energy. If anything, good flowing/balanced/cycling energy will help maintain focus and awareness and keep you centered. Now if it's all unbalanced with blockages, that might be a different story.
