They say that people are divided into two groups. They are morning people and owls. I strongly can say that I am an owl. I am used to working in the second part of the day, especially in the evening. My the most productive time is 6.00 P.M. to 9.00 P.M. I have a lot of energy at that time and my mind works as better as possible.
I have a rule which I try to follow to work productively. I usually have some rest after the university and work and then my best time comes. I am full of emergy and rested. To make the important work successfully, I usually start from the most important or difficult things.
In conclusion, I can say that it is very significant to learn your best hours because knowing this information you can give your best without undue fatigue.
