I think we all progress without even noticing. If you progress so fast you did notice you can feel rather satisfacted... But if your boss asks you can you do "This Very Fancy Nasty Difficult" project, you might think, hey! I could try, but dont bett on success. Then once you started, it seems as if all those mountains crumble and you flow through the project as never before.
in reply to At what rate are YOU progressing?
Now there is a kick for ya!
Just be patient. This moment (or one like it) will come and it will rock!
