Links on goal setting

I've been doing an internet research on goal setting recently. These are the links I find helpful and worth reading:

1. http://topachievement.com/goalsetting.html - 7 easy steps by Gene Donohue

2. http://www.mindtools.com/page6.html - thorough article on the Mind Tools (which is not fully free)

3. http://zenhabits.net/really-simple-goal-setting/ - nice and inspirational article on goal setting by zenhabits, which made me a fan of the blog
