You can attempt to push through by sheer will alone. In fact, you can do so for a surprisingly long time. While it might work as a strategy in the short term, it is rarely sustainable in the long-term. What you think is in your circle of control is very often at best open to influence, and might be entirely dependent upon luck. Recognizing that is the first challenge. Knowing what to do about it comes next.
I write a lot. That is an unavoidable truth. I’ve been putting my thoughts on this site on a mostly-weekly basis for several years now. While having an audience is valuable—and I’m grateful for the feedback that I do receive from readers—in many ways the person that I am most writing for is myself. I write to think, and I think to learn. Sometimes what I have to say surprises me as much as it might stimulate thought for someone else. And that is entirely the point.
