Sometimes I feel my job is so boring with everyday life looking the same. On the first or the last day of every month (Not sure about what you mean by this), I have to get on my work and my manager just believe I should do so. I feel extremely tired and I hate it. I want to change. Many times I have to learn new thing all by myself and in fact, I don't think the knowledge on my textbook is that useful, because it's not practical. For example, I don't understand the term 'value-added' tax and it's just too difficult to me.

value-added tax is called GST(goods and service tax) here in Australia, which is the most common tax in peoples' everyday life. I hear ppl talking about GST on TV, and it seems to be based on the idea of 'to tax more on rich people and less on the poor' -- because the rich tend to buy more expense products/service and as such they would be taxed more
