Lynn makes an excellent point.
I suspect that most "secrets," successful tactics and strategies on how to make money with all the different elements of internet marketing are covered in one forum or another... most of which are free.
Practically everything one needs to know and do to succeed online is out there, being openly discussed by people who have already successfully done it.
But who has
the time to read through the thousands of threads on all the forums, separate the
real gold from the "fool's gold," and then actually implement anything they've learned -- before it becomes outdated?
Many people
(I was one, but I've become "enlightened") do
not put a high enough value on their time. They will balk at buying an ebook for $60, but think nothing of spending days, weeks or even months of their precious time scanning various forums and other free resources, then trying to figure something out by trial and error!
Few of us have unlimited budgets. But all of us have LIMITED time.
Good ebooks (and other info products) enable you to learn faster, take action faster, and earn money faster.
Isn't that what it's all about?
