I'm twenty years old if you're wondering my age.

I walked to my class today and as I walked, I passed maybe three or four females but my eyes and mind was focused, fixated on a single thing. Like I was on a mission. I didn't look anywhere else but the road ahead with driven eyes. Not terminator eyes but like you had a goal and would do anything to get it done.

Now the reason I ask is because as I did, from my peripheral, I saw some females looking in my direction and strictly at my eyes and they were holding it until they passed my shoulder and behind me but I didn't care. I needed to pass a class and got focused. Now, I naturally don't get such attention so maybe my body has done something to display this confidence or ambition outward? Some even walk slightly in my direction. Say we were parallel, she'll go at a different angle to slightly get closer like \ | if any description works.

Another question is I'm facing the door, and there's this female who keeps looking my direction and at the door and I swear to the lord I can feel her looking back and forth through the class at me but once class is over, she's gone and away, doesn't even look back. For your questions, the clock is on the other side of the room and not a lot of people pass so I'm wondering what's the deal or maybe seeking a distraction?

EDIT: I'm stuck on body language and eye contact because it has unconscious information one can decipher and understand from an outsider's point of view. Shit's powerful.

TLDR; Was busy, IDGAF attitude to those around me, caught attention without realizing it. Also, some female looking in my direction often. Seeking advice from seddit users on their own knowledge and experience.
