I don't write for pay, but I've been writing for pleasure--for myself--since I was eight.
Whether it was journaling or poetry, I was always busy putting pen to paper. That's just how I process. I'd say that other people have only seen 1% of what I've worked on or written.
Before I was a mom, I spent six years immersed in the poetry scene here. (This is how I met my now-husband.) I was part of a group of self-described 'guerilla poets' (we read on the street, spontaneously) and did readings with the group out at gatherings, on the street, crashed Wordstock, read out in front of the library for National Poetry Month each year. After a while of this, started to be asked to come read my work on my own. It was very validating. My husband is a great editor and we'd help each other fine tune/finesse our poetry. This has led to some fun claims ("I've read at Powell's!" )and I've made some new connections into the community, like when I was asked to read at a tap dance showcase, of all things.
When I became pregnant, I became 'allergic' to the scene, so to speak. I was tired, I was fuzzy-headed by 6 pm and I couldn't stand the less-lovely sides of hanging out with poets. My brain stopped putting words together and I took up watercolor. A few months after Kiddo was born, I started a new kind of writing, one intentionally focused on parenting, helpful suggestions, and immersed in my life with Kiddo. Hence, the blog I have now.
I have a book I'm working on from time to time. It's going to take a long time because, unlike some of the previous responses, I am not a disciplined writer. I have become very disciplined in other aspects of my life and for now, have decided to leave writing as a pleasure I can keep for myself. At some point, I hope to go further with it, for now, it's something I look forward to.
I suppose my point in all of this is this: try it out in your quiet moments, as a hobby. No pressure. Just writing down a synopsis will be a start. If you have ideas to share, start a blog. You can always take it down if you aren't happy with it. I can tell you that my blog doesn't have a ton of hits by any means, but it is a good outlet for me and I get feedback from friends (often not on the blog but in real life) which is encouraging. The bigger picture is that following my natural tendency to write has changed my life significantly, even without all the fun, memorable moments. Ultimately, though, I do it because I enjoy it.
