Where did I put that idea for my best selling novel?

As always, while writ­ing the lit­tle (very lit­tle) bit below Mal­com we seem to have found once more the despair to write. It is a com­mon event, some­how we end up writ­ing one thing and sud­den­ly our head is full of ideas about nov­els and all those sto­ries that were to be but aren’t to be any more.
Per­haps this time we will set our sites small, on some­thing that is tru­ly achiev­able (no there is a strange look­ing word). We are remind­ed of an old say­ing that we can’t remem­ber… some­thing like “It’s bet­ter to reach for the stars and miss than to aim for a pile of ‘shit’ and hit it dead on!”. Strange­ly we could­n’t find the exact quote out there on the net, but we did find this which seems to cap­ture the theme:
“I’d rather be a could-be if I can­not be an are;
because a could-be is a maybe who is reach­ing for a star.
I’d rather be a has-been than a might-have-been, by far;
for a might have-been has nev­er been, but a has was once an are.”
