The most important thing about becoming a writer of just about anything is finding one's "voice." This is not a weird, artsy near metaphysical thing, or at least, it should not be treated as one. Your "voice" as a writer is what makes your writing interesting and readable. This is true if you're writing about child care, about a gadget you are reviewing or if you're telling a story.
Figuring out what your "voice" sounds like can be a little intimidating. Most people do not analyze their own writing. Some people over-analyze and are excessively negative about their writing.( This can be both a bad and a good thing. If you feel you are in need of improvement, you will work harder at it. On the other hand if you are too negative you can cripple yourself as a writer.) Some people believe that their writing has no need of improvement--and they may or may not be wrong. Some people are just writing for themselves and it shows because no one can understand it.
