What's the difference between performance, energy level and mood?

Mood = state of mind/mood (good/positive vs. bad/negative)
Energy level =power/drive (high vs low)
Performance = concentration/directed translation of drive into action (high/good vs low/bad) 

The data analysis illustrates possible corrleations between mood, energy and performance. Please be aware that the dimensions might differ. 

Here are two examples: Martin had a bad night and feels absolutely whacked when waking up in the morning. He is frustrated about not getting enough sleep and reacts irritably to comments from his colleagues. As a result he's in a bad mood all day long He could still work relatively concentrated and finished a lot of his tasks. But he did not have enough energy and motivation to meet his friends in the evening, He is exhausted, goes to bed right away and falls asleep immediately for a change. (High performance, low energy level bad mood) 

"Martin could not fall asleep last night and rolled along in bed for hours until he finally calmed down. The next day, he still wakes up before his alarm goes off. He is suprised that he isn't tired despite the fact that he had a rather short night. He is full of energy and starts the day with the feeling of being able to move mountains. At work however, his mood worsens. The day is very stressful and his colleagues are annoyed. Martin might be motivated and full of energy but he can hardly focus and only finishes a few of his tasks. In the evening he feels an urge to exercise so he goes out for a run He feels unsatisfied with himself and angry about the long to-do list waiting for him at work. This anger almost equips him with superpowers and he runs twice as fast as usual (good performance, high energy level, bad mood) 

It is quite usual that all three parameters are stand at a similar level This means you feel good (mood), motivated (energy level) and perform accordingly (performance). Or you feel bad, lack energy and can't concentrate well. But there will also be days when the three parameter stand at different levels as was the case for Martin in our examples. Especially sind your energy level can also be influenced positively or negatively by caffeine or alcohol.
