Is craving unskilful because it fuels craving?

For most people it's not readily discernible why sense pleasures are unsatisfactory. In general, a lot of people know intellectually that sense pleasures are impermanent, and that virtuous thinking & acting is what makes life fulfilling. Craving as a feeling, on the other hand, when investigated, is stressful because it disturbs the stillness of the mind. Okay, enough of rambling: From a Dhammic point of view the maxim "a little of what you fancy does you good" therefore doesn't hold true, does it? Since craving of any sort cannot permanently be ceased by means of giving into it (actually it usually grows stronger), one is advised to change one's attitudes towards it and, as best as one can, abstains from it. Am I comprehending this correctly? Thanks
