As for you...I don't know you very well, so the following is a very crude guess at best:
You have the longing of a 4 definitely down. You ask too many wistful, self-reflecting questions, to be an 8. While an 8 can and certainly will do that - as our Dj here - you lack their...innocence and cuteness about it. For you, this is a daily regime, not a ponderance you just happen to stumble about. It is definitely focused on you and your emotional state. You live here.
However. I'm going to guess you're likely male and your typical 4 fantasies probably resemble being an 8. You admire them and their qualities - like many of us 4s do - and it is something for you to strive for. Something you use to inspire you in coping with reality when you need to, and to help you escape reality when you don't feel you can cope. All 4s have their specific, unique fantasies of who they are secretly inside. Of how they want to be and how they can be in control and powerful in their very unique way. You may be doing so by looking at the 8 - or a stereotype persona you desire to embody that is an 8 - for those answers. I did the same with 9 and parts of 2 for a long time.
Then there is the smile explanation of course: you possibly have an 8 in your tritype.
