Being Aware of Negative Bias and That It's Temporary

Yesterday I was afraid for a while, then managed to focus. This morning I wasted 30 minutes from the scheduled time to wake up but then recover. 

In office I was struggling but doing quite fine. After lunch it is very hard to concentrate. 

So I remember again my post yesterday, that I need target. Well, apparently my target is not realistic yet. I want to quantify it in terms of number of hours I can concentrate. 

But my best friend in office feedback that the measure now is simply to be aware that I am now in a negative bias. Meaning that my emotion is valid, but it is more negative than other times. In other word, I cannot say that tomorrow will be like this again or at least not putting forever in my current emotion. 

Another thing perhaps is to acknowledge. Today I did not do well. Let's try again tomorrow. And the focus is not to do well. But to be aware that it is possible to have negative feelings. So the more important is to get back up everytime I fall.
