If I were able to go back in time and give myself advice I would say that all the things that we think in high school, such as homecoming queen and being class favorite is not going to matter in the future. All of those achievements are great while they last, but your education and career is going to be more important. I would also say that focusing on learning how to be a better student and studying are going to be huge factors in college and its important to always put forth your best effort.
If I could go back to high school, I would have told myself to start getting ready for college then. I would have started taking college classes my senior year. I also would have started saving for the cost of tuition and books. I would have studied harder, so that when I got to college I would have excellent study skills. That would have improved my college experience greatly.
Goto College and fulfill your dreams now, it is much harder after having a family and going back later.
