What should your first task be when you begin a new lesson

Be punctual. Without a doubt, punctuality is a key element to start a class on the right foot. I know that it is not always easy to get very punctual, because on many occasions we must move from one class to another. However, on other occasions we wait for the bell to ring to go to the bathroom, drink water, look for our school supplies, etc. This causes us to rush to class and have spent between five or ten minutes. All this time that we lose before arriving at the classroom is a time that later it will cost us to recover once we are inside.
