what is true and what is not..

When it comes to the world of development everything related, there is always a line of thought that you should follow. - Most of the time, You pick up exactly what the code means and what it is you need to implement, while learning something new, but sometimes it comes to learning from live lessons.
This means that you will be learning SOMEONE's way of working a code, and, I have talked about this in a earlier post, this usually means you have to know how the person teaching thinks while coding. Most of the time it's as simple as learning yourself from a book, but sometimes you need to translate from that person's teaching "language".
