After working for 7 years in 4 different airlines around Asia my word of advice is....go.
Go have some fun and fly in different and challenging conditions...it is not easy and you will have some difficult times adapting to the culture (depending on the country) but it is worth it if you have a few years to spare...be careful with the company you choose since not all of them will give upgrade you.
I have a few friends working for EVA and they are happy. They, like me, have been through hell and back and they are happy to stay there for a career.
Good luck and never stop having fun flying
