This is what Lexa tells people when they ask why she writes. Apparently people look at her funny, but it isn't really that much different than the responses other writers give. Ask any writer why they write and they will have a different response... if they've ever actually stopped to think about why at all. For some of us, writing is kind of like breathing. We do it and we don't necessarily stop to think about why.
While so many people out there have thought about writing a book, they may never set pen to paper or fingers to keyboard. Just having a story in their head isn't sufficient motivation to actually write it out and share it with the world. There needs to be a deeper why, whether they can articulate it or not.

Proofreading is a truly important step and should not be skipped no matter what is being published or posted anywhere. While it is possible to read a piece/post full of errors, it is also a pain. And it leaves the reader frustrated by the lack of care taken by the author of what they are reading.
And do NOT entrust this process to a computer spelling or grammar check. A spell check picks up spelling errors, not usage errors and typos. A grammar check is only as good as whoever programmed it and often makes no allowance for grammatical grey areas and unique voice expression.
Our favourite proofreading trick is to read the piece out loud, preferably to someone capable of providing feedback on what they're hearing. While time consuming, reading out loud will highlight all the typos and misused words/phrases. You'll also suddenly hear all the awkward passages and unnatural sounding dialogue and numerous other things which slip under the radar otherwise.
We guarantee the time taken to read out loud will be worth it in the improved quality of work.

These days public libraries are so much more than books on shelves. Maybe that's what people think of when they hear the word library, but most libraries are so much more.
Yes, the average library does have shelves full of books... on every subject under (and including) the sun, as well as magazines, movies and music (in varying formats), graphic novels and manga, foreign language materials, and (at least our local library) video games for various gaming consoles. Some also, by way of their websites or computer systems, provide access to ebooks and other online materials.
And yes, most libraries have computer terminals and internet for public use. Printing anything may cost a small fee per page.
Yes, you will likely need a library card, although some provide guest passes to access some services, but library cards are generally free.
Libraries also have librarians who can be wonderfully helpful people. (Treating them with respect helps. A lot.) It's their job to answer questions or help you find the answers. Also to help locate materials in library or help with placing holds on materials or putting in requests for inter-library loans.
Most libraries will also (we love this) purchase recently released books at patrons' request. So if you don't feel you can afford the cover price of a book, request your library get it. You can read it without a hit to your own wallet. Even better, the book is now on the library shelves for others to discover and enjoy.
Libraries also frequently offer programs and events of all kinds, from storytimes for children to public lectures to reading clubs and writers groups.
Seriously, look up your local public library today. If you aren't taking advantage of it, you could be missing something really great.
