From my research, it takes approximately 300 prescreened survey company sign-ups to reach anywhere close to a full time wage (say $2500 to $5000 per month Cdn$)

I went as far as signing up with top rated http://www.surveyscout.com and for a relatively small fee, I got access to their data base. I found about 100 sites that were open to Canadians (out of about 450). However most of survey companies were offering prizes or draws with few actually paying hard cash. Some were offering a point system with redeemable pay-outs in coupons or product discounts and/or free products.

While it is nice to receive products for free I felt I worked for them and really it was payment for work I did. The prize draws are nice but if I really want to gamble with my time I probably would have a better time going to Vegas. Even though odds are much better in Survey Prizes.

I managed to sign up with about 100 companies through Survey Scout and I am receiving about 3 to 6 requests to complete surveys every day within a couple of weeks of initial sign-up. That is not bad for a response but a long ways off from my goal to earn a living at this.

Overall, though, inventions either succeed or fail, depending upon need or desire for product by consumers. Let's face it, if something is not needed or desired, no one will buy it, no matter how clever it is! Even Thomas Alva Edison (he invented light bulb), failed thousands of times before inventing many successful products, as did famous British inventor, Sir Clive Sinclair. One of Sir Clive's "famous failures" included an X-Bike that was a cross between a pair of scissors and a bike. Thomas Edison's biggest failure overall was a mining operation invention which would separate iron from more low-grade ores, and Mr. Edison spent his fortune and lost it eventually, trying for a successful "invention method".

Inventors, though, are seldom deterred, and continuing to try and invent eventually leads to extreme success, as in cases of both Thomas Edison and Sir Clive. Successful inventing entails a certain number of steps or processes that will routinely lead to successful inventions:

A. The realistic assessment of invention's potential. Let's face it, if it isn't "needed or wanted", it won't sell.

B. If a patent is needed. In some cases, believe it or not, it is not.

C. The legal protection of ideas. Not allowing ideas to be stolen or copied.

D. The development of a marketable product. Besides being needed or wanted, a product should be affordable enough to build that prices will appeal to a consumer.
