Writing is useful in so many ways. I just read a post on The Art of Nonconformity about writing a Big Life List.
I've done variations of this and found it to be very useful. I wrote a list of writing goals here in this blog at the beginning of the year, and am on my way to achieving them - I hope!
The other day I found a list of life goals I'd written many years ago. I'd put it away in an obscure place and came upon it. And guess what? I'd achieved the majority of the goals I'd written there! And that happened without looking at the list after I'd written it. I think writing it down makes it more concrete, lays it down in your synapses somehow, so that you take in the goal unconsciously and start moving toward it.
It may be time for me to form another list of Big Life goals. Maybe it's time for you as well? Check out the links above to see ways to help yourself. Take your time, be concrete, think beyond adventure goals (climb Mt. Everest), and consider publishing the list somewhere. All these things can help you have a life that's more fulfilling as you go through it.
