In college you could survive on 2 hours of sleep, but now you will need all you are able to get. You will be so busy doing lesson plans, preparing for different activities, and going to siminars that life is just going to pass you by. Try to remember to take time out for yourself. Trying to please everybody at the same time. Find some humor in everything you do.
Life is to short.
I know you have heard this before, but you will really come to know what this really means as the school year draws to an end. This is very important. You will find yourself grading everything from bell work to every homework assignment ever given. This is not good. You need a system.
