before you quit, you have one more thing to think of-when can you get a new job?
if you quit but still unable to find a new job say within the next 3 months, how are you going to answer to the interviewer?you can't say "oh I quit 3 months back but unable to find a job recently" right?if u want to take a break, make sure you save enough for at least 3-4 months, then quit...it took me 4 months to find a new job after i left the previous one.....but the 4 months break was worth it
