If I could travel in time to the beginning of the school year, I would tell my past self to stay focused and to keep working even when you don't want to. It's very easy to fund yourself distracted online, on the phone, or simply doing other tasks but its so important to prioritize getting the hard stuff out the way first. Procrastination, lack of motivation and straight laziness may feel fun at the time but it's never worth it in the end. Past me, would be told to stay focused and allow my hard work now, to pay off greatly in the future.
