Your work is a lot more predictable than that of either the folks doing the hiring or the folks being hired.

Well over 99% of my work has been thrown out. (I'm a software engineer & entrepreneur.) I think I calculated that when I was at Google, the half-life of my code was roughly 1 year, i.e. after a year, half of my code would be ripped out and deleted. So after 5 years there, 97% of it was gone. The remaining 3% had made a few hundred million dollars in revenue. It's been similar (but worse) in the startup world, where I had 4 ideas that all failed in my startup before Google, and 10 so far in the startup after.
