Boredom at Work ① You might find yourself staring at the clock, willing it to move faster so the boring workday will finally end. If your job offers little in the way of stimulation, there are steps you can take inside and outside the workplace. ② If you're bored with your job, it could be a sign that you've mastered the basic requirements and are ready for more of a challenge. You might not have been in your position long enough to request a promotion. Still, you can take steps to enhance your current role. Ask your boss if there are any projects you can help with. Volunteer to train less experienced colleagues. You'll feel more stimulated at work and also increase your chances of future advancement. ③ If you feel there is nothing left to learn in your present position, take steps to increase your knowledge. Your company's website might have online courses you can take during your slow periods, with your manager's permission. Enroll in training classes your company offers in areas that interest you. You also can pursue educational opportunities outside of the workplace, such as college classes, industry-specific training programs or self-improvement courses. If the knowledge you acquire doesn't help you in your present position, it might eventually help you move into a more fulfilling position. ④ Look for ways to challenge yourself. If your job involves performing repetitive tasks, set a quota for the number of times you can accomplish a particular task during the course of a shift. This will give you something to shoot for. If you have co-workers who perform the same tasks, make a friendly wager to see who can do the most. You'll form stronger bonds with your colleagues, and your employer is likely to notice your increased productivity. ⑤ According to psychotherapist and career coach Nina Ham, boredom at work might be a symptom of dissatisfaction with your personal life. Finding sources of stimulation outside of work can have a positive impact on your attitude toward your job. Seeking counseling for an emotional issue can also be of benefit. If your personal life is going well and nothing you try seems to improve your engagement level at work, it might be time to consider a job or even a career change. If your job offers you little stimulation, there are steps you can take（）
