Is he Singaporean? If he is, then he is maturing early – this type of anomie usually hits thoughtful Singaporeans in their 20s. There are things about the education system here, including that transition to the labor market that can burn people out and lead them away from thinking about deeper matters. If he is a thoughtful person (or an idealist, or wants to think about deeper things), and he is in this system, this reaction is actually quite healthy – to a point….. the thing would be to adapt without losing those aspects.
If he is an expat, in non-local (international) schools, then maybe something else.
Well, it is hard to tell without more information about him.
