A variation on an old adage “Writing is easy, but editing is harder.” (It will take me half an hour to prepare a one hour presentation, but a couple of days to prepare a 15 minute talk, etc … ).
A condescending thought maybe (relevant to wisdom), but it is interesting in the blogosphere, particular development blogs, for the (relatively) young and inexperienced, learning their own lessons. Nothing new under the sun, but learning beats teaching nevertheless.
I think it was George Bernard Shaw who once wrote to a friend ‘please forgive the length of this letter; I haven’t had the time to write a short one’.
That rings a bell Sam … as I say it’s a very old meme that new people learn every day.
