When writing an essay in high-school you where always told to create a rough draft and get it edited so that you can correct the draft and have a strong essay. Pseudo Code is essentially the rough draft for coding. Pseudo code is important because it allows you to read code in human language. This will allow you to tell if the logic of your code will make sense or if you need to correct it.
In this picture I am writing out what I want my code to do and making sure it makes sense. After confirming that the logic is sound it is easy to create the actual code because by that point it would already be written out in human language. You just have to convert human language to code so the computer can read it. This is the reason why pseudo code is important for planning out code.
