Consistency always brings results. Staying up at night to work is really not easy but if we continue to practice it, we may master it. It is natural for our bodies to demand for some rest at that time. But if we have important tasks to meet up with, we would be left with no option than to go against nature a little bit. For someone like you who repairs phones, if you don't wake up at the time light is available, you would be prepared to face your customers during the day. Eating light foods in the night like yours is very nice too, the body sometimes needs to be lured with some delicacies inorder for it to allow us do business properly.
