If you'd like to be more flexible at work, try to be more willing to take on new projects. So, if your manager asks if you can take on a small side project, say "yes," but only if you know you have the bandwidth to do so. Maybe you tend to cut conversations with colleagues short. Try stepping away from your desk for a few minutes and converse with your coworkers. You don't have to get into long discussions as that will limit your productivity, but it can help you learn how to handle interruptions and make time for others. Additionally, positive interactions at work can help make employees feel more valued.
