Seven 10-day and one 20-day Goenka Course but no "good results" I have attended seven 10-day and one 20-day Goenka course, but never experienced either the "subtle sensations" or the "free flow."  I have stopped going to Goenka retreats because I get frustrated hearing about how after the first day I should be experiencing such and such, etc.  I still practice anapana for a couple of hours a day and study the Dhamma, and am resigned to being apparently incapable of having these experiences, which they also say are not important, lol. However, Goenka talks about them over and over in the courses and about how various people get "good results." I wonder if others have this experience also, and how they have dealt with it.
I would suggest you try another vipassana lineage. Goenka goes for body sensations only (AFAIK, later they add mind objects, but I only have 2nd-hand knowledge about it). Use a technique where all 4 foundations (body, feelings, mind, mind objects) are used from the very start could be useful; I am personally doing Chomtong-style practice (Ajahn Tong, a variant of Mahasi, dry-vipassana with lower concentration) and being exposed to e.g. difficult feelings and learn to acknowledge them and let go is extremely valuable for me. What I also find very useful is to have regular interviews with teacher on the retreat.

Meditation has good results if you have more clarity, understanding or yourself and others etc; in short, if your life is better. Experiences come and go and have little long-term relevance (despite the mind trying to persuade us this is it in that moment).
