Frugal living doesn't make one rich, but rather it opens more doors to possibilities. Frugal living adds up your savings, but it doesn't increase your income. In my opinion, one should not predominantly focus on being frugal alone. The notion of increasing your savings and your income should be weighted equally for best efficiency, hence I try to be a frugal capitalist.
It will be interesting though, to have a thought experiment on the options one can have for budget cutting(Since the topic today is on frugality). With the assumption that misery is not in the equation, here is the list that I can come up with.
1) Borrow instead of buy, especially for books. One can find neighborhood libraries everywhere in Singapore now. You can borrow dvd movies and internet connectivity in the library too. Think of it as a government subsidy.
2) Take the train to work and
Try to get a better price on insurance. Call and ask around to make sure that you are getting the best price out there. Consider taking a higher deductible, too.
6) Drink plain water. You don't need any other alternatives. Boil tap water and store in your fridge. Imagine the amount of money you can save from not buying commercialized beverages alone. You will become healthier from this. Bottled water is also handy when you are out for a meal. It saves you money, as it prevents you from ordering overpriced drinks that most restaurants serve.
Here are just a few examples I can think of. It is important to find a balance to match your lifestyle. Do not take anything to the extreme.
