At this stage, we're getting close to the root of your algorithmic anxiety. It's time to identify the algorithmic idols that are causing you to lose sleep.
Think back to the first time you heard someone mention the term "Big O Notation". Was it at a cocktail party? A conference? A coding bootcamp? The exact origin of your idolization isn't as important as the fact that you now have a deep-seated fear of complexity and performance metrics.
Write down your algorithmic idols on a piece of paper and post them below.
Once you've listed your idols, we can start working with you to develop a plan to address these issues and move on to more productive things like... like actually writing code.
