-- It is not easy to get into the tenure-track position, so stay with it unless you have to leave (or you are extremely not happy and you have to go anyway);
"I got a new offer from a state university in a lower living cost area. I think I like the environment and the people there, but the salary is way belowing my current salary. What is your suggestion? THank you very much."
-- Calculate how much $$ you finally put in to your pocket after all the cost, if you have more $$ left, it is worth to go, otherwise, forget it and keep looking others.
Thanks!
