Mental exhaustion, resistance and faith

Most often than not, if is not the activity in which we engage that makes us tired at the end of our day. We usually start our day after seven or eight hours of sleep. After waking up, we are supposed to feel energized and eager to engage with life.

But sometimes, we feel fatigued even before setting our foot on the floor after climbing out of our bed. We wonder as to the mysterious reason behind this unexpected dip in energy.

We head to work, and we blindly and mechanically go through our daily tasks. We dig though piles of printed paper, we fill out Excel sheets and we grudgingly answer calls from impatient colleagues and angry customer. Although, we haven't moved from our desk, we feel drained at the end of the day.
The effort necessary to perform all the above tasks shouldn't be that monumental. It is as if there were a leak in our reservoir of energy that we were not aware of.
Its is resistence.

The resistance we unwittingly offer before each task robs us of our energy. It takes the form of continuous internal chatter innocuous retorts that we innocently utter without realizing the devastating impact it has on our mood and our ability to perform.

Expressions like, "not again!", "why now?", "i must be dreaming!" "I am not handling this", "why me?", are the main reason we feel tired after finishing the simplest of tasks.
It is like driving a car with the brake engaged.
When these utterance are eradicated from our daily vocabulary and replaced with more encouraging words like, "this is easy!", "let's do it, if we get stuck we can ask for help", "i can do it, i did something like it before".
Even if the above sentences don't exactly reflect the reality, it puts our brain in a flowing state where there is minimal resistance to the tasks at hand. There is almost no wastage of energy.
In that state, solutions to complicated problems occur to us because our thinking is roaming free unhindered by negative emotions.
