Fear of success

People talk a lot about “fear of failure.” I think I have “fear of success.” Like, what if I achieve this goal/dream and it turns out not to be what I wanted/expected after all? I’m 60, so this has happened more than a few times in my life, and the disappointment has been awful. I think it’s made me super cautious about what I choose to do, and so I usually keep the status quo.
