Best resource is mythical, it doesn’t exist. To be honest, it does not matter from whom you are learning from and from where, be it YouTube, books, papers, or blogs. The only thing that matters is that you are learning consistently.
You could be learning from a big-name tech influencer or some unknown engineer who just happens to explain things in a way that clicks for you. Some might explain certain concepts better than others, while others might have more up-to-date information.
Instead of waiting for the perfect, start with what’s available to you. Pick something that seems reasonably good. You can always supplement it with other sources. This allows you to have a high bias for action and start making progress immediately, rather than being stuck.
But remember, everybody makes mistakes. The resources you are referring to will have some mistakes. So, build a habit of understanding what you are learning and thinking critically. If you have even an iota of doubt, refer to other resources, get your doubts cleared, and resume.
In any case, you should always be ready to unlearn what you thought you knew and relearn the correct information. Stay flexible, adapt, and continue to become better every single day.
