Prompting made me a better communicator

Prompt Engineering has become a passion topic of mine. It's super fun to tinker with GenAI, to ask it questions and to optimize the way that I ask those questions.
The basic of Prompt Engineering are simple:
- Task specify a task that you want the LLM to do for you.
- Context give the chatbot the context that it needs to complete your task.
- Format how do you want the LLM to respond to you? A bullet point list? A table? A slide deck? a blogpost?
- Process if you already know a great process to solve the problem, tell the AI to follow it. If you don't, at least give it room to think.
