Cheshire ref is right; there are a few Level 4s who are bitter that they have never been selected for Level 3, and have got to the point now where they are going through the motions. Often they'll put their lack of upwards movement down to the fact that they're
a) too old
b) their face doesn't fit
c) 'so-and-so' at 12 different clubs hates them because of something that happened in 2008 so always marks them low
and most of that type of Level 4 have a story about 'that one season' where they were AA or AB and weren't taken. It's funny how they don't give a lot of consideration to the main reason:
OTHER PEOPLE WERE BETTER THAN THEM.
I haven't been a Level 4 for long but it really is a privilege. You've reached a level of senior football that most will never get to.
@Darius sounds like an excited child from the way he's been posting recently, and that's exactly what I was like when I got mine!
I absolutely love my refereeing, and prefer it to lining. I enjoy the lines and get a lot out of them, but depending on where you live, you may only get 10 middles in the season. Make sure you give absolutely everything to those games. Try to motivate your assistants as well, which helps if you're upbeat and passionate about the game.
Most Level 4s are like me. Ignore the bitter, twisted minority.
EDIT: One more thing. When you get your assessments through, employ all the willpower you have to read the prose before you look at the mark. Most people zoom straight to the bottom to look at the mark, and then often disregard the advice inside.
