Wishing for more time to write is a trap into which we writers often fall. What's more important is to make the best of the time you have. I can fit small poems quite easily into the chinks and pauses and cracks of my life. Even novelists such as the wildly successful Jodi Picoult have managed to write little bits at a time. (No, I haven't read any of her books, but I do respect her dedication.)
In a recent interview in Time, Picoult said, "When I started writing, I had a newborn baby and then I very quickly had his brother and sister. I didn't have time for writer's block. I wrote every few minutes that the kids were napping or at nursery school or watching Barney on television. Because of that, I learned how to really sit down quickly and focus when I needed to. I've always sort of believed that writer's block is a luxury for people who have time on their hands. If you don't, you don't get it."
If you're using lack of time as an excuse not to write or do whatever it is you love to do, that's what it is - an excuse. Begin where you are, and do what you can in the present moment.
