What does a peaceful life look like to you on an ordinary Tuesday?

Why do my school peers still hate me? Why did they use to call out my name and then move away all the time? I am a tough person not someone who reacts on a whim. Why do they still look at me with a smirk on their face? Do they know they ruined me?
Why might someone choose to pursue a career in chemistry or physics despite the smaller job market compared to engineering?
