Angry Birds... and cello technique

In angry birds, you get 'x' number of birds to do 'y'.  Some of the easy ones are truly easy.  Many of the later ones depend on getting each bird to hit just so - and if it doesn't hit 'just so' then you have to go back to square one and do the whole thing over.

Sound familiar?  as in 'don't fix it, do it over'.
Also struck that angry birds is ahead of practice because there is a congradulatory hurrah when the last pig bites the dust.  Maybe practice rooms need a foot pedal activated whistle that whoops when the correct thing happens.  For now, work on the inner glow.  :-)
