Can a desired Result be dependent on external people or circumstances?

The R line is always about us (and not others). What if I want my R line to be something like “I earn a promotion at work?” Isn’t this dependent on my boss, etc. deciding to give me the promotion, which is about him and not part of my model? How can I set ambitious R goals (if I’m starting from the R in the model and working up) that depend on circumstances happening outside of my control? I’ve seen other Ask a Coach questions where the Result was “I got promoted to X position” and I’m confused how this can be the R if it depends on other people’s models.
