This is one of the things on my Someday/Maybe list to post here, and as we were talking about it today I thought I'd post it now.
I've found it really helped me to discover the links between where I was at the time of writing and where I wanted to be. After writing it I could easily see the opportunities which would lead me to my 'fantasy', and things started to move pretty fast!
Excellent article on journal writing and motivation - suggests something like 'reverse journalling' - youwrite the journal as if you were writing down at the end of the day what a fantastic day you've had, then you go and do it!
How would I spend my day?
How would I feel about my life?
What kind of work would I be doing?
What would I do for fun?
Where would I live?
Who would my friends be?
What kinds of relationship would I have with the people closest to me?
