Obligatory backstory

I've been a TRP lurker for a while, same old story - not full TRP or alpha but didn't do too badly pre-LTR. Ended up in relationship which is now 2 years in (probably a mistake, but that's for another post). Chipped at and worn away to the point I no longer have the energy to put my foot down half as often as I should.

I've read the literature and keep up with the posts, so for those of you who are experienced with the TRP mindset here's my question:

How did you fully internalise the belief system/reality to the point where it's no longer a conscious effort?

Fake it til you make it, shit test 101 etc. are all great, but I think for newer TRPers (myself included) any other input from more experienced guys on truly being TRP would be helpful.
