Suggest "How to Learn to Code (Quickly and Easily)"

Suggest [How to learn to code (quickly and easily!)](https://www.youtube.com/watch?v=R2pIutTspQA) for the "How to Learn How to Learn" section, as the first link to set the context for the self-learning journey!

It also goes along with the thoughts of working hard and self-reliance spoken of in the README, by clarifying what that looks like in the context of learning to code (hours of immersion).

It is a suggestion because I am leaving up to the wider community if the tone of the video matches up with the rest of the README,

Review the README's "How to Learn How to Learn" section and compare the suggested video with the surrounding tone and guidance. If the community accepts it, add the linked video as the first contextual resource; done means the link appears in the intended section with wording consistent with the README.
