Well, to confess, this has not been an entirely 100% successful period - but It's been a constructive challenge...!
I have found that 10 minutes meditation to put myself into a completely positive frame of mind, first thing in the morning, has done wonders to mould my attituide during the day...
last thing at night, I put my earphones in, and fall asleep listening to a positive visualisation CD, and this, I am utterly convinced, has beneficially influenced my subconscious enormously...
I used to fall asleep listening to the newsnight report, "Today in Parliament" and the BBC World Service... talking about global problems as opposed to mere domestic ones! I used to wake up in a poor state of mind....
Not any more!

I recommend you try it just to test it out for yourselves....grin
