What pet should i get?

I'm a really big animal lover, and I really want a pet. I've tried a dog, cat, hamster, guinea pig, none of them worked out, so please don't suggest them. I kind of want a rat but I wouldn't have enough time for it, it seems. How about a teacup pigs, I love pigs. How about those. Or how about an iguana. I really want a pet, I need an animal in my life. Please help me, thank you.
