January is over and February is quickly coming to an end. But as this blog post points out, it's never too late to make a resolution and set some goals. The post also discusses some research on self-regulation, finding that people who followed a weight management program for two months also saw improvements in their ability to complete other important tasks. This just drives home the point that self-regulation is a general skill and that learning this skill, even in one specific application, can have far-reaching improvements on other aspects of life.
At the same time, it is important to remember that self-regulation uses mental resources, and regulating one aspect - especially if it is very taxing to maintain - can limit how much you can regulate in other domains. It's all about balance.
