you need less information than you think to take action

Starting a recent project, I read the quick start guide and only 3 out of 144 slides from the instructions. Based on this reading I clarified the objectives, requirements, and framework of the assignment which provided the critical understanding to act. In this case, I gleaned all of that from roughly 3% of the associated materials.

Examine how an expert does it

I watched a presentation from a colleague and paid special attention to his transitions and how closely he followed the script. This gave me specific insights as to how I could glue my presentation together and where there was room to put my own spin on it. This helped me learn two demos in less than three hours. The key takeaway for me was to find an expert and watch what they do.
