One thing that surprises me about people who want to start their own internet business is how they waste their money. I can understand people wanting to get away from the whole 9 to 5 rat-race. However, I cannot wrap my head around why they waste what money and resources they can work up.
It takes money to make money. If you want to start a business, you need to invest time and money into it. I recommend you never invest more than you can afford to lose, and never use money you need. In other words, do not invest your rent or food money in your business. However, I suggest you invest any excess money you make in your internet business.
If you want to just have short-term fun, then invest your extra money in games and going out for nights of fun. However, if you want to start a business, invest your money in that.
