In some cases, the argument may be made that, "I'm not the person I was last year or even last week. I'm much more capable, knowledgeable, etc." That may be true, but the one bit of reality that has not changed is the ledge. It may have become more formidable due to erosion caused by your repeated attempts.
Seasoned climbers, of course, won't rule out moving laterally in order to move up. They don't waste time or energy on a route that is not promising, and they scoff at any reliance on magic. There is another factor, however, that can kick in when it comes to careers that is, in a way, almost magical:
Take some time off several times a week for an activity that is seemingly unrelated to career advancement. Exercise is probably the best choice since its benefits include reduced stress and increased confidence. Volunteer work can also take you away from career obsessions while providing needed perspective and meaning.
Here's where the magic comes in: Your strength will be renewed, your senses sharpened, and you will find ways of getting not over but around the ledge. The key is devoting part of your time to pondering something that has nothing to do with your objective.
