I have heard people saying stuff like, do what feels good. Most of the time, I don't think they're talking about sensory gratification, but trying to find fulfillment. Even in that case, it's like you're describing. If you're constantly running to the good stuff you're going to miss the lessons that come from pain.
The counterpoint, I believe, is to be wary of people who encourage suffering. This can happen especially with ayahuasca ceremonies. There's always some discomfort associated, and so people end up glorifying it, and sometimes that can cause it.
Thanks for sharing your thoughts.
