Should I change my job in 2015 ? Is it ok if I move to another country?

Hi, I born in 25th Jan 1986 . I got bored with my current job is it ok change my job within 2015 ? Am I gonna be succesfull in my job life in near future ?

I used to live in the USA for a while and I am still wondering what would happened If I stayed there however I chose to come back t0 my country Turkey! And in these days I am considering to go back there or Europe ,in order to work and live !!! Is it good thing to do ? Do you think that I feel like that because it is in my destiny? Lastly I got back together with my ex-boyfirend on september 2014 after 2 years. Did I do right ? He born in 19th April 1986 btw. Are we meant to be together or not ? Marriage is possible or not ? Or will we meet another persons and marry than each other ?

Thanks in advance
