"Am I a worthy human being"
I don't know, I'm a Nine
Out of those, 3 is probably the best, but it's of course my point of integration, and thus fairly intimately interwoven into my base type (maybe just because I'm a Nine? I can relate a lot to Sixey issues, especially around loyalty and finding my own opinions, for instance).
My subjective feelings on my self worth are typically that I have none, so I just try to ignore them. Usually I try to bolster my self-worth through things I do. World of Warcraft currently sees the most extreme version of this: I actively pursue being more skilled than everyone else, more knowledgeable about everything than everyone else, more prepared, more dedicated, and working harder than everyone else. Then and only then can I sit comfortably in a group of people (like my raiding group) and know, without a doubt, that I'm an equal.
Similarly in pick-up groups, as a tank, I try very hard to be the warrior-fu master who has all his keys bounds, knows the inner machinery of his class like an artisan clockmaker, and is an all-round swell guy, purely so that people will love me. I even feel a bit of pressure that this is an image I have to live up to or I won't be loved at all.
Random strangers on the internet.
IRL, I've often gotten wrapped up automagically following other people's ideas for me. The person you're talking to now is largely a caricature of myself because my dad wanted me as a kid to be more friendly and bubble and blah blah. The person I play on my warrior is a caricature as well in that he's very self-aggrandising in a really silly, ironic way. I pretend to be someone pretending to be someone with a huge ego (in a really silly way, so that people pick up on the fact that it's not entirely serious). Going the hard yard to learn my class really well and play it as damn hard as I can is sincere though, but patting myself on the back in party chat for being badass is not.
I've also always been drawn to performing. As a kid I wanted to be a stand-up comedian (I also wanted pokémon to be real so I had guardians and companions I could rely on, and I always loved Oak telling me how fantastic the relationship between me and my pokémon was and how we were BEST BUDS and the POWAH OF FRIENDSHIP HELPED US PREVAIL, but that's probably neither here nor there). Nowadays I'm fascinated by genuine acting, even if I'm completely frustrated by my lack of talent in expression.
