Leave your baggage at the door

If you were to ask me what is the most frequent mistake new Go programmers make?, I would not hesitate to tell you that it's bringing other language patterns into Go. I know this was my biggest early mistake. My first Go service looked like a Java app written in Go. Not only was the result subpar but it was rather painful, particularly while I was trying to achieve things such as inheritance. I've had a similar experience programming Go in a functional style, as you might see in Node.js.

In short, please don't do it. Re-read Effective Go and Go blogs as often as you need to until you find yourself using small interfaces, firing off Go routines without reservation, loving channels, and wondering why you ever needed more than composition to achieve nice polymorphism.
