Agreeing with everyone just to avoid friction means nobody actually knows what you think.

Constant agreement makes you pleasant and unreadable. Each small nod costs nothing on its own, and after enough of them people stop asking your opinion, not out of disrespect but because they have learned your answer will match whatever was said last. The peace is real and you paid for it by becoming invisible.

Pick one low-stakes thing this week and say what you actually think, politely and without a long defence. A film, a plan, where to eat. Almost nothing happens, and a few people start wanting your view on bigger things.
