I will have published more than 300,000 words by the end of the year, so I'm confident I can keep up this daily writing habit for at least another year.
When I don't feel like writing, I imagine what I will achieve if I overcome the resistance. 73,000 words if I write 200 words every day for another year. 365,000 words if I project myself over 5 years. 4 million 300 thousand if I live another 60 years. It's gargantuan. Probably more than 99% of the people on the planet, perhaps more than most writers.
Sometimes, it's not enough to convince me to lay a few words, so I instead imagine what I will miss out if I stop writing. I won't be able to write books. I won't have the means to share my passion or remember the worth of my past days. Heck, I wouldn't even feel worthy to help fellow writers with my code if I wasn't one myself.
No, no. There is no way I can ever afford not to write. Writing is too pleasurable, too vast of a craft, all too necessary. I need to write, more than my writings need me.
Having the will to write is 90% of the work. Finding ideas, drafting, researching, editing... are all just details. There is always a way to write, a framework to apply, or an app to use, but the will is often what's lacking.
