Every moment in High School. I know I sound like a parent here, but to all you kids still in high school listen up:
I'm not that much older than you so I can definitely feel for you. I know that high school can be wretched and boring and terrible and you feel like you have no say, but really take people's advice when they say "enjoy it while you can - these are the best years of you life." And they truly are, and sadly I learned that too late. I took too many things for granted in high school and only now a few years later, looking back, wish that I had embraced that time more. It is a feeling you will not feel again for the rest of your life, so really - although at times it seems awful - you will miss it like hell after you graduate. Okay that's it for now.
