One of most important attitudes you can have is willingness to invest in yourself and your knowledge.This is quite different from investing in "opportunities" to make money.
Investing in yourself means you are building skills that you can use in your life. Within context of internet marketing, investing in yourself means spending money and time on materials that get you ducated on this business.
It may be marketing, site design, copy writing, email campaigns, search engines or any other topics. There's no shortage of information. In fact, I often say that information overload is our #1 occupational hazard.
Still, you can't stick your head in sand and expect to build skills necessary to succeed in this business.
Certainly, payoff can be huge. I know dozens of people making six figures in this business. And many others making a nice supplemental part-time income. Working from home. No boss, etc. You know dream, right?
