When i'm walking down the street where am I supposed to be looking? eye contact with strangers feels needy and looking down feels low test and looking straight ahead feels try hard and looking up at buildings feels like you're a tourist

that's why you should always stare at girls' boobs by default. less threatening that direct eye contact .

I look at the sky with my mouth open so people think I'm communicating with god or that I'm staring at a UFO.

or you look like a total retard

You are the definition of autism.

look kind of up, so that you can scan for dead tree limbs.

dead branches are no joke and kill 45,000 americans every summer.

Do all of those, but don't commit to a single one. Make eye contact maybe once if you want. You can also wait for when they're looking away to look at them, so you appear confident/alpha out of the corner of their eye.
also if you want to look nonchalant, check your phone from time to time. Don't be glued to it tho, don't want to look like a neet with 2 feet of depth perception waiting to run into something before moving out of the way

Look at your phone like a normal person

hmmm

This is bait surely
