May I suggest a different approach: you don't need an external teacher to learn anything, you are always the best teacher for yourself.
Simply read, think, try, fail, repeat. I've never approached learning any other way and it's always worked for me.
i think it is too difficult to learn and know about such a huge website and system. if some one is a newbie he must get information from some one.
You have to take it in section's I think if you look at every single bit of info on the site .... there is just a ton to learn. You could study for months this forum has so many good resources and posts.
But I think pick topics learn it move on to another. For example first just learn very beginner bitcoin information, don't jump straight to white paper unless you are petty technical. Then maybe learn about mining, trading, alt coins, etc. You will find many topics and pick what you want to learn next.
Also one of the biggest thing is when learning you will find things you enjoy learning. Certain topics I would hope you dig in and really love to just keep reading and learning. For example for me I love mining. I read it daily and still learn things. If you spend time on the site you will find something you enjoy and it honestly becomes fun learning.
