"I am a writer"

I read an article yesterday written to assist new authors.  The piece was full of seemingly helpful information on how to promote your new book.  The author listed many ways to expose and stir interest through the internet like social networks and web-sites and one called Squidoo lenses, which if I understood it correctly is just a silly name for web pages.  It's all very overwhelming to me.  I have limited abiltiy and knowlegde of the internet.  You have to realize that I am of the erra of the huge computor game called "Pong".  Pong was a computer game wasn't it?  I didn't learn how to use a computer until I was in my 30's.  Plus I am a bit of a slow learner.  I did however conquer "texting" last year and have become quite prolific at that task.  U no ? I mean? TTYL about that. 

While reading the article, I jotted down notes to refer back to when trying to create my Squidoo lens and link my web-site to my networking pages...it sounds like I know what I'm doing but honestly, I haven't got a clue how an RSS feed works and don't know the difference between a URL or SEO.

Once I got past all of the computer stuff, the author stated that as an Author one must be  a salesman of themself.  He went on to state that "who could sell yourself better than you?"
I am struggling with that part.  I am NOT a salesman.  Oh I could sell others but I'm having a really difficult time selling of myself.  My friend and author Jame Kirkpatrick says I need to look in the mirror and say "I am a writer."  I snickered when she told me that, and she scolded me for it.  So she is a professional writer and trained mental health person so I will try and take her advice...here goes.  "I am a writer."  "I may never be a famous writer, and that dosen't really matter, but I am a writer."   I added that last part myself.  I really do want people to read my book and to "Like" it.  So I guess I need to get busy and start selling of myself as a confident writer...man, I have my work cut out for me.
