People only give value to a thing if they have, at some point, been uncertain as to whether or not they'll get it.
Paulo CoelhoIf you want to achieve your objectives, you have to be prepared for a daily dose of pain or discomfort. At first, it's unpleasant and demotivating, but in time you come to realise that it's part of the process of feeling good, and the moment arrives when, if you don't feel pain, you have a sense that the exercises aren't having the desired effect.
