I've turned my focus inward for way too long. I've done it in a sub optimal manner I admit, by getting wrapped up in the rationale, but I've opened myself more and more to my intuition and the inexplicable(for now). Right now I need to find the balance between being focused inwards and outwards, because I can't be stuck in my own mind all the time.
Therefor I think your advise needs some explication if you are willing :)
I think MBT is beautiful, but it mostly appeals to the ones choosing the warriors path, while the path of service is one to equally consider. This world needs help, and not only by people helping themselves will it get fixed.
Focusing inward for me means peeling back the layers of SELF for the purpose of eliminating fear. I have achieved inward/outward balance by accepting the reality that I am consciousness occupying this VR body. You can be on the warrior's path and the path of service.
