[stylist] motivating myself to write

[Vejas Vasiliauskas]

Hi All,
I was wondering what you all do to motivate yourselves to write 
when you feel stuck.
It was easy for me to write last year because I was in creative 
writing class, so if I wanted a good grade I had to write, which 
I thought was great!
I have lots of different characters in my head.  I conduct 
stories about them all in my head as well, and know their names, 
ages, personalities, etc.  But often when it comes to me wanting 
to write about them, I open a document and just freeze.  I really 
want to keep writing, though.  I just find it strange that I have 
all the information about them in my head but when it gets to 
having to write it on paper it's totally different.
Has anyone else had this problem?
Any suggestions on what I can do to get my creative juices 
flowing in the written word?
Thanks,
Vejas
