It could be. But the author is [clearly I thought] speaking metaphorically about purpose.
Here I’ll try: [I’ll probably fail at it]:
“Wanting to achieve” means you lack something.
You are less of a person than you might be one day.
You are empty, void, incomplete, not whole, in a sense, an error waiting to be corrected.
Following extrinsic motivation (worldly visible rewarded achievements) means the world decides when you are complete, whole, finished, purpose achieved.
