Heather Gleason Posted about 2 years ago What were 5 things you wish you knew as a senior in high school? I would say, what you learned in school will have little relevance on your life as a whole. While the memories of your school days can be cherished, the learning will not affect other stages of your life. You will evolve and change constantly that even how you view your knowledge will change. You will realize that so much you are taught is opinion and lies. Try to think for yourself!! True knowledge is not learned from a book, but by experiences. So, go into the world and experience as much as possible. But, be wary. The world is not always very nice. Be true to yourself, nonetheless.
