You know you are too tired when

you washed your hair at 10 a.m. in the morning and at 3 p.m. you began to wonder if you put shampoo. And guess what? You washed your hair, but did not shampoo it.

Too much in my head. Too many things to do, too little time, but still coping. Need to get back on the track.

Shampooed my hair at night. First time in my life that I bathed and washed my hair but forgot to shampoo it.

Need some rest. Continue with the work tomorrow.

Missing those days when all that mattered was how to cut the donuts so that everyone gets equal share.
