As others have said the key strategy is patience. If the correct decision is to fold, then you need to keep on doing that, even if you have been card and/or "situation" dead for a long time. But you might also need to study preflop ranges a bit more. It sounds like, you are playing a very static range, and this is not correct. Rag aces for instance are typically always an open, if it folds to you on BTN or sometimes even CO. And if it folds to you in SB, often you can play any two cards or any two cards except complete junk. So rather than giving BB a walk, maybe you start limping in even with a hand as bad as J2o, assuming there is an ante. And maybe you need to defend your big blind significantly more.
Sometimes in an MTT session I find myself with incredibly nitty stats across tables. Like maybe my VPIP is 12% on one table, 9% on another and 13% on a third. And while its possible, I have just been card dead across tables, its also a wake-up call, that maybe I have not been paying enough attention, and maybe I have defaulted to much towards the easy decision of folding to avoid any sort of marginal spot. And this is a problem, because we dont win tournaments by being very good at playing aces or kings. Its all the other marginal spots, which separates the winners from losing or breakeven players.
