Have you started to recognize your own habitual thought processes and patterns of behaviour, and break free from them? I think this is the most fundamental step towards integration, once you know yourself, and know how your 'system' works, you can then work on controlling it's energy (that's obviously the 5 in me speaking, oh the irony)
I am sure now that all 9 types do this (I've been listening in to concioustv, which has been very enlightening), all of the types have described in some way that they have habits, which can sometimes be beneficial (like for example an 8 acting without thinking too much). Other times it may be best to break out of that habit and make a concious effort to do what you are not familiar with doing.
I'm just in the process of doing this now. At first, without guidance I just tried to break free from my own type, without realizing the importance of embracing it when it is working effectively. I can snap out of it, but more often than not, but often I can't help but indulge in the patterns, and I get an intense fear in my gut when I do sometimes.
This morning, while on the bus, I noticed a guy caught in multi-lane traffic pushing his broken down car. Normally, I would watch, but not engage when things like this happen, but this time so I got off the bus and headed towards him to offer help, but he was already gone. I couldn't help feel that fear, and I had so many doubts, typical of 5s, but I pushed through it. I don't know how the 8s can do it so easily, but I could kind of feel what drives them to do it, I just had to quiet my damned head and do it.
