What advice would you give to people thinking about a change in career?
Do something about the way you're feeling. Don't remain stuck, whatever you do. A change in career might or might not be what you need, but at least understand why you're not happy. Look at yourself first to do that. Then consider what you might do with your life that truly excites you. It's not always easy to get there and it almost certainly won't happen overnight, but there are thousands of other people doing things that excite them. Why shouldn't you also be able to?
The wisdom in this advice is that career dissatisfaction may be very real but it may not be the whole story. Unless we're willing to have a good look at what's driving our discontent, chances are a shift in career will not in itself provide what we are really looking for.
