if you feel like you have a skill advantage (or knowing you will run great the entire tournament) than you should try to avoid tough high variance decisions. '
My question is-Is the proper strategy to win your hands preflop? No, you should try to win the biggest pot possible, which might mean playing the river.
I'm not sure how you can expect to win PF or OTF unless you are raising way too much that only premium hands will call your bets. if the deck is hitting you in the face
You'll want to maximize value from worse hands (not hope to win PF or with a cbet). I think a small ball betting approach is a better way to avoid variance. Yes, you'll get a lot of calls PF and will have to double/triple barrel but the pots will be smaller.
