I'm a little sceptical to making eye contact with everyone.

When entering (or being in) a venue, I believe eyeballing everyone gives a vibe of neediness, "who sees me, who's looking at me? I'm bored, I'm looking for someone/something". I can imagine an alpha having fun, minding his (group's) business, not noticing anyone else (they're not worth looking at, you don't need them, 100% non-neediness). When people start looking at you however (ioi etc), I agree on looking them in the eye and not looking away until they do, or approach immediately.

Thoughts?
