Thank you all so much for your responses, I will have to digest these a little further, however an initial thought/question or two around experiencing more pleasure than pain, more of the time:
I understand, well at least I think I understand, that it would be unreasonable to expect to experience a continual flow of pleasurable feelings, however if the pain I am experiencing does not lead to pleasure in the future, then that pain, dare I say, is to be avoided. Perhaps I am being too rigid in how I apply my calculation of pleasure vs pain sometimes??
Could you please also help me in clarifying if I have understood this correctly: that the feelings are two, pleasure and pain, if I am not experiencing one I am experiencing the the other, as there is no neutral state, or have I reduced this a little too far?
Thank you again
