I recommend tight aggressive on early stages, try to take advantage of those loose players, with that image of you on the table probably will win most of the pots that you play with Cbets or connecting on the flop and of course know when to give up that AK that miss entirely the flop and the opponents it's someone that will call with anything, the goal is at least to double your stack during the first 10 levels, try to get it cheap (Limping or Calling a minraise on BB) with hands of potential monsters like Pocket pairs that hit a set and suited connectors, abandon the hand if you miss the flop.
Last but not least avoid going all in PREFLOP with hands like AQo, AQs, AKo, AKs on early stages I would recommend only pay all in preflop with AA or KK depending on how crazy is the opponent add QQ but for sure its not worth the risk of losing your tourney life with AK preflop (remember its a flip coin 50/50 against any PP) only to double and later on the tourney those chips become nothing.
Maybe not so organized thoughts but I hope they help you to reach more ITM. Last recommendation Study ICM and push or fold strategy how to play on the bubble
