Thank you for this advice.

It's true, many people completely ignore marketing, and I did for a while. Now I'm learning, I'm getting books on it and try to fix my deficiencies.

I'll write on the blog about it. At the moment I'm reading "Book yourself solid" from Michael Port: http://www.bookyourselfsolid.com

I also have another book I just bought in the pipeline: http://doubleyourfreelancingrate.com/the-blueprint

I'll have a look at the book you recommended, thank you.
