I've been writing code in some language or another for almost three decades. My headers, comments and READ_MEs usually end up helping me more than anyone else.
When you have multiple projects in muliple languages for tens or hundreds of clients over the years, the last thing you want to do is open a project or repository and see little or no documentation. And you don't want to have to figure out what/why the heck you did in 2007 and explain the project to coworkers.
I guarantee you that clients and coworkers will pick the worst optimal time to want revisions. And if I spend the time upfront to make it simple for a junior member of my team to take ownership of a project in the future, my life becomes better.
