Optimizing.

First off I would like to say I am really looking forward to learning everything about coding and definitely utilizing the resources that I have at my disposal. I want to learn more about optimizing, and making good use of memory. Bottleneck was and interesting word I had to look it up and see what it meant in the coding world, it states "An inefficiency where the flow of the project and/or work stops or slows at a particular point". To this is what I want to master first because it seems it can make or break a project.
