I used to feel defensive when people would say, 'Yes, but your books have happy endings', as if that made them worthless, or unrealistic. Some people do get happy endings, even if it's only for a while. I would rather never be published again than write a downbeat ending.
I think perfect objectivity is an unrealistic goal; fairness, however, is not.
I think maybe people see bands and musicians as some sort of superhero unrealistic sport that happens in another dimension where it's not real people and not real emotions. So, I grew up listening to Beatles records on my floor. That's how I learned how to play guitar. If it weren't for them, I wouldn't be a musician.
It's simply unrealistic to depend on secrecy for security in computer software. You may be able to keep the exact workings of the program out of general circulation, but can you prevent the code from being reverse-engineered by serious opponents? Probably not. The secret to strong security: less reliance on secrets.
I think it'd be pretty unrealistic to think we're the only planet in the world with thinking beings. It's kind of a strange conceit. Especially given how many universes there must be.
Holidays in general breed unrealistic expectations. The minute you start wondering, 'is it going to be wonderful enough?,' it never will be.
I've learned that universal acceptance and appreciation is just an unrealistic goal.
Fiction is optimistic or unrealistic enough to demand that there should be a meaningful narrative.
I think it would be very difficult to maintain one kind of art or whatever for your whole life. I think it's unrealistic.
The most unrealistic thing I've ever read in comics is when some group of characters calls themselves the Brotherhood of Evil or the Masters of Evil. I don't believe any character believes their goals to be truly evil.
