The issue of resistance to practice is a deep one worth exploring further. From a purely practical meditational perspective, the advice is fine, but the problem is often an underlying psychological issue that if dug up, may make not only engagement with practice easier and more fluid, but aid a practitioner in accessing deeper levels of presence. Often mindfullness becomes a way of distorting our relationship with ourselves when, as the interviewer mentioned, we seek pleasent, emotional highs from the practice. In my humble experience, I'd suggest doing some sit down work with the issue of resistance either using a dialogue with the resistance itself or some other technique.
