Never forget how it feels to be new and overwhelmed. For every question that you ask, remember that you should eventually pay that back by answering one for someone newer than you.

I think a lot of times, once developers get enough experience, it's all too easy to judge or make fun of those who are new for something they don't know. Remember that you were there once and lend a non-judgmental helping hand!

When you teach people how to code as much as I do, having to explain why things like this are so wrong over and over again starts to make you die inside.
