Waiting until it's your turn to look at your hole cards?

[MrBrightside]

this is exactly what I do. I take a quick look immediately as I get my 2nd card if I'm in early position or a quick look after I see UTG's response/action if I'm in late position. Furthermore, I don't really see why it takes people longer 5 seconds to decide what you are going to do preflop unless you are a noob.

Another habit I've gotten into: memorizing suits so I never look again. this way I don't give off that "I have to check if my ace is a heart after a flop of 3 hearts" vibe. I just repeat in my head the suits... like "ace hearts, jack diamonds". Once I do this, I don't have to look again. I once won a decent size pot because of this once ... the guy said later he didn't believe I had the ace of a suit that was four on the board because I didn't look back.
