I can't work well today

Oh, it is terrible to work when you are so tired. Maybe you can drink hot water and some coffee. And then have a good sleep tonight.

You are not alone there. When I don't sleep well, the next day I will feel very sleepy and tired and cannot work efficiently and my mind seems to be slow. To make up for the it, I will take a nap after lunch. This is what I do to make myself concentrate on my job in the afternoon. Take care.

Litville, whenever i am not getting enough sleep, the next day i would feel very tiring to work as well. I usually would drink a cup of coffee to freshen my mind. Sometimes, i tried eating some dried sour plum fruits and it can makes me feel refresh as well. I am not sure whether do your area sold this type of fruit. Nowadays, i seldom drink coffee since the weather in my area here is very hot. hope you are able to complete your daily work before you return home to relax.

You need a power nap. If it's not possible, coffee would do. If you're not a coffee drinker, then tea or an energy drink would get you through the day.

There are really times that we feel so tired to do our stuffs but we need to.. In my case I just try to motivate myself and keep on thinking the reason why I'm I need to work.Just seat a goal everyday that will serve as your inspiration to work...
