#Microservices - Size Doesn't Matter!

I work as part of a team at MYOB that has been building a new platform for accountants for the past year using a microservices architecture. We're now running approximately 20 microservices in production and we've learned a lot about the right size and granularity of microservices during the project.

"Microservice" is a very loaded word, it immediately evokes connotations about the size of what you are building - what is the right size and granularity for a microservice? If I go too large am I doing it all wrong? It's gotta be small because it's a microservice , right?
