my friends say i am "all or nothing" - there is no in between. if you want it done right, do it yourself, full-fledge, no looking back. alot of that came about when i physically revamped everything about me - i mean, i always had it, but that brought it to another level. that change really made that personality/attitude flourish

This is perfect. This is what you are going to do with your brain and your thinking on 'being nice' really means incongruence.

This ability, that you can bring 100%, you are all in, is where your confidnace will come from.

Baby steps Andy .
Look for things outside the bedroom, the day to day where you are lowering your needs, placating, being incongruent. start there.
