Never think about others;

Because it is a high-cost, low-return activity.
In reality, when something happens with other people, you just sit there doing nothing.
But in your mind, you perform a storm of speculation: Is the other person's attitude hinting at something? Is their indifference emotional? How will others perceive what I do? Will it make me look bad?
Most of the content you repeatedly analyze cannot be verified, nor will it change the outcome.
Why others do things is often unclear even to themselves, yet we try to extract logic and certainty from it.
The brain's bandwidth is limited; when you allocate 80% of your energy to guessing others' mental states and predicting their reactions, only 20% is left for self-growth and perception.
