Sometimes I get complacent. I don't want to do the work to evaluate my habits, routines, processes, and tools simply because I've done the work before. As a result, I often am stuck with things that don't work, until some external force causes me to re-evaluate where I am.
I realized this was an over-arching theme in my life recently after one of my tools did just that - forced me to re-evaluate. And it's caused some churn in my life, all of which has made things better.
