The only imposition is that you are restricted to the letters on a
keyboard, and
the need to have these in a linear stream. Its similar to writing by
hand,
except that you use the names of symbols rather than tracing their
appearance.
With practice, like with any other physical skill (such a playing a
musical
instrument) it comes naturally after awhile, and you can get to be
very proficient.

You should learn to break up the task into:

1.  initial input, which allows plenty of time for exactly what you
mean by
"we often think better when we write".

2.  fixing up the inevitable errors that you'll make in step 1.
This also forces you to look back on what you have done,
and rethink parts of it, often leading to improvements.

3.  considerations of how things look on the page.

I disagree completely.

You shouldn't think of LaTeX as a programming language.
It is a way to express mathematics using a key-board.
As such, it is much, much better and easier than any other
system that you'll find.

The formal structure, of sectioning, environments, lists, etc.
actually force you to think about the structure of the information
that you are trying to present. This *does* help you to understand
it better; and may indeed help you to become better at your
chosen profession.

It starts out that way, because you are only just learning
something new. Do you remember what it was like when you were
first learning to drive a car, or ride a bicycle or horse?

After awhile, when you have become familiar with the menus
and palettes, or just more proficient at typing, this all
becomes secondary. You will get to the stage of thinking
about the mathematics at the same time as you are composing it.

Others have already replied along these lines.

Hope this helps,
