If you ever had a job you had to go to every day, you could write every day. It's always a new day when I teach in the classroom, but I go to work because I have to do it. There are days I don't like going to work because my job gets stressful. But the habit of going to work was instilled in me when I started teaching. The most difficult years were my first ten years of teaching. It got better because I learned to adapt to the situation. I knew what to expect, and I did it anyway.
I recently wrote an article on Medium that addresses the same situation. Sometimes I don't feel like writing, but I write anyway. My classroom teaching taught me how to view online writing. Even though I don't make much money writing online, I do it anyway. Here is how I keep my mindset in writing.
Things I do to help me keep writing
1. I write even though I don't feel like it.
2. I write even though I make mistakes and don't know what to write.
3. I write despite my writing not being up to par.
4. I write because I see the potential with writing ahead of me.
5. I write because freelance writing doesn't pay the bills, but I hope it does in the future.
I treat writing like teaching in the classroom. Even though I have to repeat myself many times in class, I do it anyway because I have to. Teaching the same material is repetitive. Writing is the same way. I do it over and over again until it's automatic.
Final Thought
I view writing the same way I teach mathematics. Going to work every day is repetitive. Writing every day is repetitive. If you worked full-time every day for a set period, you could also write every day. It's all a matter of mindset. I put my mindset to writing like I go to work every day.
Write every day as you go to work every day.
