Would you rather have a fun job that paid poorly or a really boring job that paid good money?

Trying to decide between two careers; a preschool teacher which pays close to minimum wage or a medical coder that pays $45,000 in my area. Being a preschool teacher sounds like so much fun but I don't know if I'd make enough to pay my bills, so I was thinking of doing medical billing and coding. It pays a decent salary but sounds boring as hell and you get benefits.
