Writing a newsletter is a long-term journey, so it needs to be approached sustainably. Don’t let short-term fluctuations (subscriber gains or losses, monetization pressures, or growth hacks, etc) drain your energy. Instead, focus on consistently delivering real value to your readers over time. If you stay committed to that, the results will follow. Those results might be fame, money, or subscriber growth, but those are byproducts, not the goal. The most meaningful reward is your own growth along this journey.
