it depends on the buyin basically, also stacks and so on,
therefore if it is a low buyin (regarding one´s
bankroll) be a little looser looking for spots to rob some blinds and try to risk a lot and increase the stack to be in a position for a deep run and the final table, no fear about being busted because one can play them several times and the goal must be win and not just get paid
but if the buyin is too expensive then one could be tighter trying to catch one of the last paid places unless one is dealt some monster hands or strong hands in a passive table then could loose a bit and risk (here are the worst moments to receive a bad beat), this situation happens usually when one qualifies to the tourney through a satty and getting paid at least will bust the bankroll
then of course exists a lot of variables like stacks, for instance if one is the chip leader of the table or at least has a big stack then one could challenge quite often the lower stacks and put pressure on them and so on
