Are you an Asset or a Liability.... that is up to you. If you
finds that you are NOT being
appreciated......
1) Ask yourself are you really doing any thing Worth being
appreciated 
Example - How many times had a person said that he is leaving
Sillypore for good.... how NS sucks.... how everything sucks....
etc. Then you are a Liability.
Example - I complaint about too much Foreign in S'pore, thats why I
try to have more children to offset the numbers, I do my NS without
complaint because others before me had done their parts, I disagree
with Govts policy... and is starting a NGO to look into such policy
(Not just TALK only)...... then you could be an Asset.
2) If you felt that you are still not being appreciated....... you
could always move to some other place where you think others would
appreciate you more..... wherever that place is......
S'pore is not really a good place to bring up a family......
that I agree.
Might be good if you could had a few more choices to choose from.
Do go to the country of your dreams for a few years...... you might
like it there, or you might want to come back. Its all up to
you.
