As part of a separate topic discussing why marketers often mislead (whether purposefully or not) clients to focus on "shocking the system" and on the wrong solutions.
As a core philosophy behind weight management - one eats within budget to ensure their weight is maintained over time. A sacrifice of one's present wants for a future goal.
In speaking with other members on and off MFP I've noted a common trend, that at one point they believed a goal was impossible. It wasn't until they managed to achieve a small goal that their perception changed and the "impossible" became reality. This in turn carried over into other aspects of their lives.
Does this core philosophy carry into other aspects of your life? Financially, professionally, academically, etc.
