Hi everyone!
This post I will consider as like a think of a scriptwriters that sometimes is overladed of ideas and some period has not any idea.
If you are in the second period you have a block. Don't worry, if you had not this block you cannot have a big idea!
Some reasons give you this wall but before you fall in desperation you have to allow for:
1- you have finished since some day a script;
2- you are too busy for writing, maybe you have other commitments in this period;
3- you are in a new location whereas usually you write always in your place;
5- you are tired (sleep more time);
6- you are just bored because you are fall in a rut and to this end you have to divert with something else such as...fishing salmons in Denver lake...yeah, I know that Denver has not a lake but if you will find a lake and salmons there, it means you also could write a screenplay.
In any wich way don't despair of it! Follow my suggestion: look for a lake in Denver! ;o)
