No,I was a teen fairly recently and love being an adult.
Just last week, I was feeling burned out and decided to take a day off from work and studying and relax. I walked around Boro Park, ate some pizza, and went home. The weather was ok and I felt so calm and relaxed and ready to jump back into things.
I could never do that when I was in high school.
Also, I love learning what I’m interested in and picking classes, and working in a field suited to me, instead of having to do whatever the schedule in school is.
So make the most of high school, but remember that what’s really going to count is your choices in the real world as an adult.
