Salary is a very subjective matter on whether earning this $x is enough or not or whether is poor or rich.
There are so many factors involve i.e whether are you sole breadwinner, got dependent etc ?
Generally I just feel that your life will generally be the same for The median salary in sg. Meaning your life won't be of much difference whether you are earning $3k per mth or 6k per mth or even 10k per mth . You still need to stay in the same kind of flat, eat the same kind of food etc
so the point is what for make yourself suffer by thinking I must earn more, I must earn more.
Yes we should aim to earn more but the more is those that will change your life kind which means so long you are an employee, things will remain the same whether you are the manager or you are the lowest rank.
As a matter of fact, I earn lesser than manager but my bank has more money than him.
But end of the day we are living the same kind of lifestyles in sg.
Your salary as a employee isn't going to earn you to own those big ticket items even your salary is $10k 15k
