concentration

Preferably before the sunrise in the morning or after sunset in the evening, you try to suspend your mind from thinking of anything. This is meditation and it can be used to achieve higher efficiency on the work/project by concentrating your mind on these projects. First learn to keep the mind celar and after you practice this, you use the meditation for attaining your aim.
