It can be a bit daunting the first few times when you realise a hobby/pleasure has become a job.
You bet!
(Even though I'm not Patti.

)
Until recently I never earned a cent with my writing, and I wrote just for pleasure. For me.
Then I got discovered. Gulp! Not in my preferred genre. Not even in fiction, but as a technical writer. Web Development.
I'll tell you guys a secret: I know zilch about web development. Well, next to nothing, and all I know is self-taught. So, I do some web design, and muck around a bit with Blogger templates (just created a new one yesterday) but it's really not all that super.
Anyways... I'm writing articles now. On web development and home education (that's more my niche, thank goodness!). I get them published and get paid for them.
And if all goes according to plan, I'll have my first book out early next year.
It's nice, and it's frightening.
Some days I feel on top of the world, and other days I just want to stay in bed and hide under the blankets. What if...
Oh man! I've been on disability for all of my adult life, and now that I'm finally earning some money, I'm scared silly. I want to be able to make a living from my writing (not nearly there yet), but what if things go wrong? What if I loose my allowance and then find out that I'm unable to produce enough stuff people will actually want to pay me for?
So... on top of getting more organised, I'll also need courage. A lot of that!
