Mind energy consumption
Then we can assume that some of the time we spend our mind energy and other times we recharge it. We use our mind energy during our studying or working time. We simply recharge it when we are free from our work or study commitments. From this we can summarize: When our mind is concentrated, it consumes energy. When it is relaxed, it gets recharged.
There are at least three factors indicating energy consumption. The first one is direction of observation. When we focus on the outside, our mind will be with 'things' outside such as work, people, problems, situations or environments. Each moment we let our mind roam outside, it will spend energy. The second factor is expectation. In our life, working time is important. It means the chance to create convenience or prosperity in our life. Also to be professional, we seem to have no right to make any mistake. The more working quality we expect of minds, the more we concentrate with it. The more we concentrate, more we consume our mind energy. The third factor is number of 'things' we are coping with. The more elements that float in our mind, more it spends energy.
