Too true Rebel, but investing wisely is also an investment in lifestyle in my opinion, as the freedoms that come with having more money and fewer stresses from not having several hundred thousand dollars loaned from banks are going to improve the quality of your life as well. You can ignore interest rate hikes for eg. You can have the freedom to not work for the man and possibly do something that you actually like doing for a day job.
My goal 10 years ago was to make enough cash on the ASX to buy the house I want in the suburb I want without borrowing any money, which I have done. This too was a lifestyle choice, as now instead of giving a bank my hard earned cash, I can do whatever I want with it and have a better life as a result. Of course i've missed out on living in my own home for 10 years, so that's the trade-off.
