The first of rule of doing work that matters:
Go to work on a regular basis.
Art is hard. Selling is hard. Writing is hard. Making a difference is hard.
When you are doing hard work, getting rejected, failing, working it out, this is a dumb time to make a situational decision about whether it’s time for a nap or a day off or a coffee break.
Zig Ziglar taught me this years ago: Make your schedule before you start. Don’t allow setbacks or blocks or anxiety to push you to say, “hey, maybe I should check my email for a while, or you know, I could use a nap.” If you do that, fear is quickly trained to use that escape hatch again and again until you do nothing.
Isaac Asimov wrote and published 400 (!) books using this technique.
The first five years of my solo business, when the struggle seemed never-ending, I never missed a day, never took a nap. (I also committed to ending the day at a certain time and not working on the weekends. It cuts both ways.)
In short: show up.
If you show up regularly with generosity, everything else is gonna take care of itself.
The people that are doing work that matters are not doing work that is popular. They are just doing work that changes some people.
