Memoir writer to fiction writing. Possible?

I went to school for writing. Memoir was my specialty. My life can only be written so many ways.

I took some fiction/storytelling courses but since that wasn’t my focus (and it’s been a couple years) I wanna dabble in fiction.

I’ve had a ton of story ideas but don’t know where to begin. I’m a full time working mom so time is limited but writing is my escape. Advice?
