You know the Beatles track with the longest name “Everybody’s got something to hide, except for me and my monkey”? I find this is the “retrospective song” (follow link for some tips and tricks on retrospectives). “Everybody’s got something to hide” means we’ve all made mistakes, now it’s time to face the results. No matter how bad it turned out to be we tried our best, trying out crazy new ideas. For those ideas that turned out to be a success, now the time has come to celebrate what we’ve achieved, time to slow down and “Come on let’s take it easy” (retrospective time). Let the monkey out of your sleeve (a Dutch saying) meaning “finally the truth comes out”.
