8 Tricks I Learned about screenwriting

From this guy, http://jamesgunn.com, who wrote Slither. I don't want to be
a screenwriter, but it's writing and it's very hard, so I still found
some inspiration in this:

"Remember, these are 8 TRICKS, not 8 RULES. I believe each of these gives
a person a greater chance at becoming a successful screenwriter. But NONE
of them are NECESSARY to becoming a screenwriter (although the last one
comes pretty close.) Here goes:

1) Write at least 3 hours a day 6 days a week.

2) Move to Los Angeles. Of if you can't do L.A., move to New York.

3) Spell check, of course, but also make a pass checking for "its" and
"it's", "their" and "there," "your" and "you're", and so on.

4) Don't even think about trying to get an agent until you have completed
your best possible work.

5) Don't blame others for your failures as a screenwriter. By assessing
your own responsibilities, and learning from your failures, you
supercharge yourself and become unstoppable!! (NOTE: it's good to read
this trick out loud and pump your fist up in the air while doing so).

6) Got friends who like to cut you down and tell you "this isn't possible"
and "that can't be done"? Lose 'em.

7) On the flipside, have 3 good objective readers, who are very honest,
even harsh, and who have your best interests at heart. (Mary Harron agreed
with this trick, but added that you should make sure the objective readers
at least somewhat share your tastes -- that is, they have the same goals
you do).

8) FINISH WHAT YOU START. Are you doubting what you write? Are you
starting to think it's crap? Good! That's a part of being a writer! We are
doubting, tortured, angst-filled souls, and all it takes to be a writer is
to write in the face of that!! "
