There is one who does....

When I was working as a IT volunteer (actually getting paid, for a NGO) in Africa (Chad), I heard a proverb more or less like this:

il y en a un qui fait
il y en a dix qui ecrivent des livres sur ce qu'a fait celui qui fait
il y en a cent qui organisent des conferences sur les livres que les dix ont ecrit
...

which translates to:

there is one who does
there are ten who write books on what the one who does has done
there are a hundred who organise conferences on the books that the ten have written
....

Very often it's the same in IT.
