Things that have a common quality ever quickly seek their kind.

People and things gather according to what they already are. The company you end up in is rarely an accident: it reflects what you value, what you tolerate and what you find funny, and then reinforces all three. The room you are in is both a result of you and a cause of the next version.

Look at who you have spent the most hours with this year and ask what that group takes seriously. If the answer is not what you want to become, you need no dramatic exit, only a slow change in who gets your evenings. Proximity does most of the work either way.
