(This is mostly me trying to motivate myself. But if you need a good kick in the pants, feel free to join me.)
So you wanna be a full-time author? Wanna get paid to do this all day? Wanna work from home, with your cats and your coffeemaker?
You’ve done the planning. You know where you’re going, and how to get there. Now what’s the first step?
Write your words.
Tired? Too bad, write your words.
Cat threw up? Clean it up, then write your words.
Feeling uninspired? Start with something, anything, and write your words.
Other things to do? Self-doubt? Not enough time in the day? Worrying about whether this whole thing will even work out? Just plain don’t feel like it today?
Too bad, so sad, get off your lazy ass and write your fucking words.
You don’t get there by being lazy. You don’t get there by being hesitant.
You get there by working your ass off, sacrificing, and then working some more.
You can sleep later. Now it is time to WRITE YOUR WORDS.

My new mantra “write your fucking words.” Just what I needed– thanks!
You’re welcome!
I hope it helps (both of us).
It’s the only way to do it! But also, the words have to be pretty damn good.
