I am fairly new to options as well. I've been trading for a while but started trading options this year.
I have found the most important decision I made that has helped me trade unbelievably better is to always have a plan. I ask myself questions like 'Why am I selling/buying here? What are the possible scenarios that could happen? How am I going to react? When am I going to exit this trade?'
I find that if I can answer those questions before I enter a trade, I do much better. My emotions stay out of it as well if I have a plan.
