Close, but not quite. I'm more german than austrian.

Actually I'm doing my PHD on adherence to healthy habits and behavioural change (preventative medicine with a focus on exactly these things). ;) The whole willpower shtick is a bit overplayed based on the available evidence. The real (first) problem is often learned helplessness. And then a lack of knowledge on how to change things and which things are most important. Shaping your environment and changing your habits without using significant amounts of willpower. It's doable.
