Vow of Purity. Should be easy enough.
Vow of Hygiene. Also easy.
Vow of Devotion. This is just part of being in a relationship.
Vow of Fitness. I really need to be doing this anyway.
Vow of Kindness. I try my best not to be a dick.
Vow of Wealth. I don't want to be a NEET.
Vow of Health. I also need to make myself do this.
Vow of Fortune. Yeah, fits with Vow of Wealth.
Chose not to do Vow of Frugality because I like being able to go out and enjoy myself sometimes, Vow of Disconnection because no personal internet at all is too harsh, Vow of Effort because sometimes you just want to do something for fun, and Vow of Stability because affording a place on my own isn't really viable in this economy - we need a two person income. Vow of Fate should be obvious, as should Vow of Friendship.
Anyway, that's 9, so I'll go for a Complex Avatar.
