I agree. Wonderful advice.
A trainer on a course I did a few years ago on IM gave a good example of this when someone asked 'how do you get started?' He said you'll never mow the lawn, sitting on the couch with your feet on the coffee table. Starting is simple. You get up, walk outside, pull out the lawn mower and fill it up. Before you know it, the lawn's mowed. All you have to do is start the rest unflods as you go. We often get stuck 'thinking' about it.
