Its up to your interest and motivation...whether you'll like
doing the job everyday.
The job is either to be in the skies, in an E-2C or G550, watching
radars, communicating, directing planes, assessing situations. Or
on the ground somewhere in Changi, watching radars, talking to
planes...
If that's what you'll enjoy doing, go for it.
You must love the job to stay the long-haul la.
