I've only been asked once how to get into writing. Good thing--I had no answer because there is no one-path-fits-all, or even one-path-fits-most.
But since then I've looked for what others have to say on the subject.
My Author Tool Bag features sites I use in writing, editing, and marketing. It's
stuff I've found online. The usual caveats apply--no recommendations either
expressed or implied, don't click on blind links, have a good antivirus, etc.
You know the drill.
