Similar to my "How to be a Better Junior Developer" talk, with some new content, including incorporating my "Ask vs. Guess Cultures" talk.
Abstract:
Most developers focus on increasing their technical knowledge. However, there are many aspects to working as a professional developer besides coding proficiency. If you have interests or experience in other fields, you can pull in even those non-technical skills (like building relationships, project management) and immediately increase your impact on a project or team. When you mentor someone, you can help them play to their strengths and ramp up more quickly as a result.
