If you notice that during the day you lose your life force, which you can spend on something more valuable, then you should reconsider your daily routine and change something in it.
You can independently identify your problem areas and simply replace them with something more useful.
It is difficult to imagine how much a person is able to influence his own life, when it will be profitable for him.
Put the goal in front of you, find out what is so exhausting during the day and do not repeat it again. Some people suffer from the fact that they do not have a clear plan of action, while others are on the contrary from the fact that their day is too overloaded with the schedule and in case of the slightest deviation from the schedule, then it is necessary to constantly adjust themselves to the established framework. All these actions take our forces, and at the same time, that energy which is simply necessary for normal vital activity.
The loss of liquid is also knocked out of the force. If you drink not enough water throughout the day, this can cause you to become sick sooner or later.
