Let your next job teach you something before deciding it must justify your entire decision to leave.

A new job carries a heavy load when it is asked to prove that leaving the last one was correct. Every dull week becomes evidence, every problem becomes a verdict on your judgement, and the ordinary awkwardness of learning a place turns into something ominous. That pressure can push you into calling the whole move a mistake long before you have the facts. Early months are information rather than a ruling.

Give it a set period where the only question is what you are learning. Write down what is genuinely better and what is not, and read that back monthly instead of nightly.
