This US News list is intended for Students off to college, but I’m actually challenging all of my high school clients. Why wait until the summer before you are off to college…these are all things that will help you both in high school and college.
I will take the challenge as well:  Reading / Relearning / Time Management / Do something outside home and family / Investigate Career Options.
