Think that you are too busy to write?
Try 10 minutes. At some point in the day: morning, lunch break, right before going to bed, whatever works best for you. Take that moment and whatever tools used and write. Do that every day for a month and see how far you get.
If that works really well, maybe try for half an hour.
For me. I have too much time. I could be writing 3-5 hours a day, if I could be dedicated enough. But I get distracted with other things. (another topic for later). Writing often is something that I need to work on, like many of my fellow writers.
