Try something new in your job
Assuming your company values you as an employee, one of the first people you should go to when you find yourself losing interest in your job is management. If you excelled in your current position, they’re not going to want to lose you. Ask them if there’s something else that needs doing in the company – in another department, preferably. Sometimes, the only way for us to appreciate what we’ve got is to have it taken away – temporarily. Lots of companies have interesting schemes that involve inter-department transfers between valuable, but jaded, employees like yourself. Explain to your boss that if you continue where you are, you’ll become hopelessly disinterested, and your performance will be adversely affected. Don’t close your eyes to new opportunities, where you are. When you get back to your current job, you’ll find that spring in your step you thought you’d lost forever.
