On being devoted
It never ceases to amaze me how some famous writers and researchers are able to churn out so much work. They seem driven by their respective professions and specialties. They eat, live, and drink what they do—and they never seem to tire of it. And it goes without saying that many of these people are not, indeed, mentally ill (ie, they aren’t doing what they’re doing simply because of overcompensations or some other defensive tactic). How are they able to accomplish all this? Looks like their secret is this: They deeply believe in what they are doing.
Carl Rogers, for instance, believed so much in the tenets of his person-centered therapy that he not only wrote about it to his dying day, but he got energy to keep up his research program and his therapy by adhering to person-centred principles in his own personal life.
