career guidance: 25 September 1981 (Metal rooster) born 2pm

i received a promotion with a small pay raise this year but i am not truly enjoying my work as i do not find any meaning or satisfaction. I have decided to stay on simply because i have made many good friends, but i do not know how long more i can endure. May i know which is the best month or year to switch job and what jobs or fields are suitable for me in general? thank you!
