The Internet offers aspiring writers tremendous opportunities. One can build a good fan base, by way of it. One can get noticed, via it. One can get published, through it.
Still, with so many opportunities to write and interact online, it can become overwhelming.

Pressure, too, can also build. That is, if you feel that you must do/attend everything pertaining to writing, and the writing life. I call it the "what if I'm not in it" syndrome. That is, you involve yourself with everything "writing," because you feel that if you don't, you'll never become a good writer or "noticed."

Contests, Internet book parties, and other types of writer celebrations are all great. If you can attend those, that is fantastic!

However, as an aspiring author, you need to know your limits. You also need to accept those limits. If you don't, you could stretch yourself too thin, be pulled away from your goal of writing, and encounter writer's block.
