Organizations can do that to a practitioner. Personally, the culture adds a large part to my Wing Chun journey. If it wasn't for the enthusiastic attitudes from those that I train with, along with a supportive community, it would be a completely different path for me. Also, traveling to Hong Kong, training and learning from native Cantonese speakers and Chinese customs in general have also helped me retain my desire/passion to stay the course. In the context of Wing Chun, I find it important to remember that
it is Gong Fu, and Chinese Martial Art traditions are its roots. I have learned that so much information is literally lost in translation, it has a profound impact on the experience of fully understanding the concepts of the system and training in general. That's something often overlooked or even unwanted by Westerners.
That's not to say I haven't been there... After discovering that the first group I was with wasn't a fit and I had no chance at completing system, I had to part ways. I was out to discover and explore the possibilities of what Wing Chun really had to offer, not what an organization had to offer me. During that time I was Ronin, but that actually helped me to grow. I never gave up investigating, researching and training Wing Chun with as many people as possible. I discovered that for me, it was about Wing Chun and sharing knowledge, not about the individual (myself or an organization). After meeting several people, making friends within the community and traveling, I was eventually welcomed into a lineage that is full of practitioners that simply want to expand their knowledge and get better at their craft. It's infectious.
I know I have said this before, but If you still have the passion don't hang it up, your situation can improve. I'm still encouraging you to get out of your zone, fill the gaps that have been held back from you, experiment and work with other groups to gain different perspectives on Wing Chun. Travel for a weekend, go to a workshop, meet new folks with a completely different explanation about sections, a training method or concepts and then take them back to your group for R&D. I know of several friendly workshops that accept anyone from any lineage, and I can promise that you will walk away smiling and ready for more. You can always moonlight while you explore your options, none of your WT people have to know anything
I have trained with several high-level practitioners well into their 60's that owned me in Goh Sau, because of experience. Most of them think way outside of the box, so much so that they don't have to define all the terms, set limits or adhere to the rules that some organizations have misinterpreted over the years.
