Strategy on the table MTT

Many beginners ask me how and which strategy is most efficient to use at the beginning.
There's no pre-established pattern because poker is a storm of ideas involving people. And every mind is a world unto itself, so imagine how many worlds exist in the universe?
One of the strategies I usually use at the beginning of a target tournament is identifying each opponent's plays and style. This is fundamental to having a basis for knowing who to attack and at what point or position at the table.
What seems like a lot to you might be just a few chips to others. So you start identifying certain patterns in a particular opponent and begin to chip away at them little by little, thus increasing your stacks to stay in the money until you reach the money.
What do you think of the strategy I highlighted, and if possible, can you improve it? What are your preferred strategies, and who do you usually have the most success with? Your participation is extremely important for us to add value, from beginners to veterans.

I really like the idea you highlighted about observing opponents early — I think that’s one of the most underrated edges in the early stages of a tournament.

That said, I’d slightly refine your approach by adding structure to the observation process. Instead of just “watching players”, I try to categorize them quickly into simple groups:
– tight/passive
– loose/passive
– tight/aggressive
– loose/aggressive

It is important to put labels, but it's not just labels but also to analyze what moment of the tournament they are at to know what decision to make
