Why is it called summer BREAK when it's not....

So even though I am out for the summer I still have tons of work to do before my Psych rotation in July.  Reading chapters, doing remediation, and then doing more studying to prepare for my class. Guess what...I haven't started yet.  It is so hard to continue working my butt off, not having a break, not seeing family, etc.  Please GOD help me get motivated for another year of this!
