Thanks for the specific details (see below.) They make it much easier to
know how to respond.

In General
---

Talking, and sitting (for long periods) at a computer, are strong stimuli,
and it's easy to stop looking after yourself during these activities. It
gets easier with practice.

When you "do" the directions, perhaps it's because you're "homing in" on
your head-neck in an unhelpful way, or trying to feel the directions
working. Both of these will sabotage you.

Don't spend more than a few moments on "let my head forward and up" before
moving on to "let my back lengthen and widen". You are not trying to fix
your neck, but to coordinate the whole of yourself.

Also, stay connected to the outside world. One way of doing this is to keep
consciously registering what you're seeing out of the corners of your eyes
(at first, practise this while you're walking.)

Sitting at a computer, talking to someone, and/or giving directions, the
temptation is to "concentrate", and to blot out everything else. But keep
letting sensation in. "Attention" is Alexander's word for the kind of
awareness we want-- one in which thinking always includes what is happening
in ourselves and around us. It's in contrast with "concentration", which
blots out everything except what we're doing (including an attempt to blot
out our own bodies, very often.)

In Particular
---

To encourage yourself to use your peripheral vision while sitting at a
computer, make sure you have an interesting environment surrounding your
desk-- a view out of the window, photos of friends and family, a sport you
enjoy, whatever. Change it often. And when working, take breaks, inhibit and
direct. Slow down.

At home, at work, at the computer and away from it, do "Whispered Ahs"
regularly, making sure you keep your peripheral vision active as you direct
your head, neck and back. Let me know if you want more information about
Whispered Ahs.

I hope this helps, and please report back, in the spirit of experimentation!
