Remember, you may enjoy it but school is work. It’s great to enjoy your job, which means that at first you won’t resent all the extra time you put into it. But if you keep on putting that extra effort in, you will start to resent it, and so will the people around you. Also if you put in lots of extra effort and don’t put anything back into you then that is when you are at risk of burning out. Your brain is like a bank; withdraw too much from it without making the odd deposit and you will feel a deficit. Your body will tell you you are stressed.
