I was never rebellious as a teen. My sister kept me in my place more than my parents ever did. I once tried to become punk and people thought it was cute...not what I was going for. I think it's because my parents allowed me alot of freedom because they knew they could trust me and I understood the logic behind any stipulations they placed on me.
I am 23. I have no current plans on getting married. That being said, if my life had turned out differently I likely could have been married by now. For me, the way things are going, I'll be surprised if I am married by the time I am 30.
I do and don't follow my heart. Depends on what happens. I have followed my heart when it comes to love and this has had not so good results. ISFJs seem to give and give and give and when they finally give up and walk away...its a big deal. I often wonder if people realise what they lost when that happens. I tend to not follow my heart when it comes to more logical things - for example, as much as I loathe my job, I know it is something I need to do for now with the intention of it becoming better at some point.
I have never dated an ENTJ...so I couldn't tell you.
I adjust my cleanliness level to whoever I am living with or how busy I am. LOL
