How You Get Fatigued

Fatigue doesn't come from working too hard, it comes from anxiety and sense of non-achievement.

Where Does Fatigue Come From

Fatigue doesn't come from working too much, it comes from not finishing the task and sense of non achievement and anxiety that comes from it. Meaning, if you are not able to finish a task, it makes you more tired and creates anxiety. So, focus on finishing tasks, even if it is a very little one, instead of working a lot. If you finish a task even if it is very little, it is going to give you a lot of mental energy. If you don't get sense of achievement, no matter how hard you work, it is not going to satisfy you mentally and as a result you are going to be fatigued all the time.

Also if you just sit there and not do the work, the anxiety that comes from it will also make you fatigued. Not working actually makes you more fatigued than working because all the anxieties build up
