Okay, maybe I'm overdoing things a little. (No, wait... I'm not.) The point is, Christmas is a huge holiday for everyone, whether you're a retailer, a member of the clergy, a parent, (especially) a kid, or anyone else who loves the excitement and promise of the season.
For the sponsors of the Blogging from A to Z April Challenge, April 1 is kind of the same thing. It's something we prepare for almost as soon as May 1 of the previous year. Every year we do the Challenge, we want it to be better than the previous year's. For us, that means encouraging people who have participated in past years to participate again, and to bring their blogging friends, and their friends, and so on, and so on, as the old shampoo commercial used to say. The A to Z Challenge is truly a time when "the more, the merrier" applies.
So, it's never too soon to start encouraging people to start thinking about April. And that includes inviting you to start thinking about participating in the festivities, and about people you think might enjoy the Challenge. Bloggers you admire, people who you think would enjoy themselves. You might meet some bloggers (or potential bloggers) during the upcoming NaNoWriMo, or in the other "blog hops" you do every year.
It's also never too soon to start thinking about your theme for the upcoming year. Maybe this is easy, because you use the same theme every Challenge. Great! You can start thinking about your entries. Maybe you try to think of something new every year. This would be a good time to start. If you have trouble thinking of a theme, you might want to see what other people have used in years past. The list of blogs who participated in the 2015 Challenge is still available; feel free to browse the blogs of other participants. Maybe you never use a theme. That's all right! You can always begin planning your word list for the Challenge.
You might think 163 days is a long time, but you'd be surprised how quickly it passes. Personally, I can't wait! How about you?
