Snow White is popular, benevolent, friendly, sweet, hard-working, caring, optimistic and resilient. It's definetely better than being lonely, unpopular, resentful, vindictive, malicious, lazy, pessimistic and not very compassionate like me.
The only trait of Snow White I am glad to lack is her naivete. I am a pretty good judge of character and I like it.

Cinderella was likeable and admirable.

Nah. Tiana tends to be a workaholic, self-righteous, easily angered over precious little, restrictive towards what others say or do, and generally just meaner to people than she needs to be.

Belle is self-righteous, sneers at the poverty and the day-to-day living of her neighbors while she lives off of her father, spends her time reading fairytales, not science, and she doesn't make any true effort to socialize.

I am like neither one, and will never desire to be.

I wish I was as optimistic as Snow White, maybe not as nice/trusting (I think it's a detriment in the modern world) but to have such a positive attitude would help me a lot as I can be pessimistic/cynical.

Ariel is fearless and determined and while I could perhaps do well with more of that, she has too many flaws I either don't want or has in tenfold next to me that I simply don't need more of.
