Too much information and plans that we want to do. When we think about them all at once there will be chaos in head's mind so there will be more emotional pressure and also at mind. So we should filter inputs in brain activity so it can clean mind, more focus, and has less pressure in brain activity. So for making better productivity, do what we can do with maximum focus by just think and doing things at present first and filtering mind, not thinking about  past and future anxiousness.
