@syz, that’s the same feeling that caused Faust to make a bargain with the devil.
I agree with skfinkel. It sounds like you don’t have anything to face that’s difficult and challenging. Maybe you need to take on a role at work that stretches you more, or set yourself a task that you’re not sure you can do. It doesn’t have to be carrying a ring to Mordor. It could just be learning how to do something you’ve never done before and then doing it, whether it’s hang-gliding, crafting with stained glass, or speaking French. Or volunteering for something that few find easy but that people do find deeply satisfying, such as hospice work.
If you’re not getting enough out of life, try giving something more.
