I am retired, but busy with lots of projects on the go including internet marketing. So far I an affiliate of Freebieforce, SFI Marketing, Marketing Pond/Global Team Club and Traffic Wave.
I live in British Columbia in a deep mountain valley and head to Mexico for the winter. The nice thing about internet marketing is that its portable.
The main reason I am into Internet Marketing is that I got a little tired of the usual "old lady occupations" and wanted to learn something new. I have so far learned to build web pages using NVU and a smattering of html. Now I am learning PHP and for awhile I had WAMP installed on my laptop so I could experiment
I really do believe that anyone can earn income on the internet. It will take time and perseverance. There is something here for every skill and knowledge level. Many affiliate programs have excellent training resources. All you have to do is read and follow through. Many programs are either free or very low cost. One thing to take into consideration is whether a particular program has some use or benefit other than its potential earnings. Freebieforce and SFI both have monthly fees but also offer useful products or services.
