Management has always taken my estimates, put them in a drawer, and then blamed me when the estimate was wrong.

Of course, they ignore the fact that the requirements changed during the project every single time.

That said, every project I've ever worked on was "new ground" and had never been done before. Musk can estimate how long it will take to make the next Tesla but might have a bit of trouble estimating the opening of the first Mars colony.

There was a posting about estimating that talked about walking in California. It was perfect. Can't find it again though.
