Maybe you could have an adjacent cell with a formula like:

=if(a1<"","","Please Fill In A1!")

format in nice big red letters.

And if you have any important calculations, you could add a check to make sure
that the cell is completed before you show the results:

=if(a1="","Not until you fill in A1",yourcalculationhere)
