Your copywriting will always be awkward as long as it
represents a "forced" effort to sell.

The main thing is to write every day... and read copywriting
stuff every day, like the classic books:
-John Caples
-Joe Sugarman
-Claude C. Hopkins
-Robert Collier
-Gary Halbert
-Eugene Schwartz

... even a little - reading sales authors and books about
sales psychology is good too. You don't need a huge...

Robert Collier has been called the great "reason why" copywriter.

It's easy to look at his subject matter - peddling books, raincoats
and briefcases by mail and dismiss it. "That doesn't apply
to me - I'm an info-marketer," we say.

Which leads to $47.00 ebooks. "That's the optimum price for an
ebook," we say.

Optimum for who? Why ever would your prospect think he was
getting a fair shake paying...
