"You know that exercise routine you've been talking about starting up in January? Well, forget about how virtuous it is, or how healthy, or how it might boost your confidence. Instead, think about putting on your sneakers and tying them, one at a time; entering the front door of the gym and walking to the first treadmill you see; stepping aboard and starting to move your legs, right leg first." (The 2 experiments suggest to choose concrete thoughts about a task, vs the abstract how's and why's) - David Lynch
