Parents....friend or foe?

It always amazes me how growing up your parents are the first to say "great job!" "Keep up the good work!" and other encouraging things. They are always the most postitive and encouraging ones. I can remember countless times when my mom would tell me I did great on something, even if the grade on it was a B or below...Then I hit junior high and high school. What is it that makes the comments go from positive to negative within 3 months?! For the last six years, I have heard the positive comments like "you can do it!" or "good job!" maybe once every month or so. Otherwise its basically "Oh well that was good but you could have done better" or the oh-so-famous one "It just wasn't good enough." Since when did our best become our failure? Many parents are happy with their kids' success, but then there are those select few who are never content. I for one have parents who never attended college. One is at a dead-end job and the other unemployed. I plan to attend college for a degree in health care, but it just isn't good enough for them.......I'm beginning to wonder if my best will ever be good enough.....
