It's the same dilemma that i'm facing it's disappointing getting so far and profiting the minimum, what i absolved is that late stage variances are way bigger, liking or not you gonna need skill + luck, depending the size of your stack will allow you only to play only one strategy PUSH or FOLD. And if your stack is healthy you're going to have selective aggressiveness (like you're on the button and raises the BB because you know he is TAG player, or just bully someone who has the smallest stack on the table), the size of minimum bets represents a considerable percentage of your stack, so one mistake and you're out. And with you're at mid stack size don't get involved against deep stack enemies unless you have good hands, defending your BB from stealing is going to be crucial too.
I wouldn't recommend trying to bully the smallest stack at the table... they have less to lose & often ICM won't be an implication when making their decision. Often, it is better to focus on stealing from med-sized stacks, ones who have more to lose.
OP, read up on ICM. It will help with final table play.
