Personally, some of my best memories of high school and college come from my final year at each. You've achieved so much and the future is bright. While you may already have something lined up for post-high school, try to remember that discipline will take you far. If you stay motivated and continue to work towards the end goal now, then you will have momentum to continue your success in college. In addition, while it may not seem like it now, each day in high school is preparing you for college or something that you will face down the road. Try to view it in that light and you may find more purpose in each day.
