Love the posts by @jasonleow and @basilesamel about writing as a sport.
I can very much relate to this analogy.
So far, I haven't stuck long with any sport in my life for various reasons (mostly because I moved around a lot). I've tried CrossFit, dancing, pole dancing, yoga, pilates, running, canoe, climbing, squash, and probably something else that I've already forgotten.
Now, I'm finally sticking with a gym routine, and I'm fitter than ever.
And I'm finally sticking with a writing routine, and I've never felt better about my progress in becoming a better writer.
For me, it's not so much about a specific goal. I'm not preparing for a competition or a specific writing achievement. I just want to see consistency and progress.
Working out and writing has become part of my daily routine. Something I can fall back on.
Sometimes, when the energy is a little low, I might just go for a walk and write about anything that comes to my mind. And that's ok.
But those days are getting less and less. Because flexing the (writing) muscles makes me stronger and gives me more energy than it drains.
Working out and writing becomes easier and easier over time.
And on some great days, I can even set a new record.
