A Competent has too much of a handle on the big picture to confuse himself with an Expert: he knows what he doesn’t know.
The past wasn’t as good as you remember. The present isn’t as bad as you think. The future will be better than you anticipate.
The stages might be real, but they are fluid, and we are never static within them. We are always moving and changing.
In fact, if we don’t actively hone our craft and skills, we get worse.
Make it good enough and ship it and move on.
