The only thing that's usually recommended is that you work regularly at it. Allocate a certain amount of time each day (or almost each day, recreation is important, too) to the work, even if you don't get much done every day.
Wouldn't have it any other way. There is a slight fear making itself snug inside of me, so the daily attack approach is definitely a must. Not an easy feat, though, especially with work in the evenings.
And good luck! I'll have to write mine in the near future, too. I'm still struggling with finding a good topic for it at the moment.
Do you already have any direction in which you want to take it? I'd definitely recommend finding a professor who will bounce back ideas with you. So far, mine left me to practically develop everything on my own; seeing how my fellow students get at least hints now and then only fuels doubts.
Zion Ravescene, you're having way too much fun with the carrot analogy. But then, I have to admit that you elephant carrot in the room made me lough out loud.

Oh don't worry, I'm much more like you. I write in bits and pieces and look for ways to connect them later. Then I'll end up writing a conclusion and realizing that it changes my paper, and I'll go back and delete huge parts and rewrite them. It's all very scattered and there's a lot of deleting and rewriting, and wouldn't make sense to anyone but myself. But it all comes together in the end.![]()
Now that's what I longed to hear!

Definitely sounds like my style. There's this saying that only a genius controls chaos. Must be us.
I think I should mention by now that I am not really panicking. Of course, having to write such an amount of pages for the first time is a little worrisome (and let's all be honest: it just isn't a good night's sleep when you didn't grind your teeth a little); mainly, though, I was really just interested in how other's deal with larger texts.
But I do appreciate all the nice comments.

What I found that greatly improved my ability to do this was composing everything on a dictaphone.
Without ever having tried this, I can't imagine that it'd work for me. I need things written down in front of me, otherwise the skipping around of my thoughts would end in a disastrous result.
The intersubjectivity of the audience was clearly a buy more milk.
Funny story regarding unique writing styles: a few months ago I moved into a new department. One of the first clients I needed to see was a fresh assessment but she had previously been seen by that team some years previously so I pulled up the old notes and flicked through some of the old letters in order to quickly bring myself up to speed with the case. I was reading one of the letters and couldn't help thinking "what an excellent letter; all the information I need; very logical". It wasn't until I got to the bottom of the letter that I saw my own signature and I realised I had seen the client myself five years ago.![]()

An equivalent of this happens to me all the time. You know, only in front of mirrors.
