Don't Sleep Until You Have Done These Things First
Screenshots
Don't sleep too much, because you will end up making mistakes that cost you in business and in life. Don't sleep too little, because you will have to work too hard and take up too much of your time. Don't sleep in your bed at night but in a different room because when you do sleep in your bed, you will dream and then think about what you did wrong the next day and the next. Don't sleep with your windows open because you might forget something important. Don't sleep with headphones on, because you might not hear everything that's going on in your room.
Don't sleep in random waking up hours because if you do, you might be missing important calls or messages, and even important emails. Don't sleep when you know that your day is going to begin. Don't sleep when there are people around you or when the sun is glaring in your face. Don't sleep when you are afraid to leave your window open because it might be unsafe and you might wake up in the middle of the night or at the break of dawn. Don't sleep when you are very thirsty and when you need to pee very badly. Don't sleep when you still need to wake up in the morning.
Don't sleep when you are bored or when you can remember your lines. Don't sleep with other people so they won't disturb you and when you are having a nightmare, they won't make it real. Don't sleep when you are hungry but you don't have any food to eat. And finally, don't sleep when you are afraid to die.
