Personally when i decided to venture into internet marketing, my biggest mistake was that i thought i could use the internet to make money over night...boy was i wrong. It took me nearly over 3 years before i earned my first $ online. I wanted to do some affiliate marketing but my biggest challenge was that because of my geographical location i could not promote most products because my country was not listed as being able to use paypal or clickbank or purchase any training or course that required paypal and i realised most products in IM use paypal a lot...very frustrating!
I am still struggling though with finding affiliate networks to promote but i have managed to get around it by promoting PLR products and this is working very well for me.
What was your biggest mistake or what is your frustration?
