Working On Something New

I've started the first draft of my first ever science fiction romance this week and have already completed the first 6030 words.

After writing historical and paranormal/historical, writing sci-fi just feels like fun. That's not to say I'll stop writing those other genres, because they were a lot of fun too. It's just that switching my gears brings out a fresh feeling to my writing.

What do all of you out there think about switching genres? Do you think it's a good thing for writers to stretch their wings?
