With this realization, I utilized two techniques that worked extremely well for me.
The first technique was mirco-writing during the week. I began writing whenever I could in increments of 5 to 15 minutes. I did this before going to work, during my coffee and lunch breaks, and before bed. Every spare, and sometimes odd, minute during the day counted towards my writing productivity. A sentence here and there eventually adds up to a paragraph and then a page. This meant that I took my notebook or laptop everywhere.
The second thing that helped me was to be intentional about writing and making it a part of my daily routine rather than a chore. I tend to do a lot of my writing early in the morning when my family is still asleep. I typically wake up at 4am, grab breakfast and then get to my computer to begin writing. Some may prefer to write in the evening, at a coffee shop, or library. The time and location do not matter as long as writing becomes a part of your daily schedule.
So start taking advantage of every spare minute and make writing a daily habit. You may be writing in sound-bites, which may feel different at first, but you will be writing and doing so regularly.
