way to learn anything efficiently and quickly

Hii, how should I learn anything that is one problem to solve and you find a guide regarding that more efficiently and quickly in life particularly in business and more particularly in internet marketing? I want to listen from your your journey to success and experience in life?
PS- Don't ignore question but share your experience.

The best way? Take an actual interest in it. Don’t try to learn it, try to understand it.

Any subject you want to learn can be learned, but whether or not you succeed depends on your understanding.

*steps down from soap box*

Maybe a little out of context, but the sq3r method is pretty good when you have to learn something.

Spending hours learning everyday on a field will make you after some times professional on that field, it could be seo, email marketing, internet marketing....etc, the key is to focus learning every area and to be patient, because simply nothing came overnight, that's the method i personally use everytime I want to learn new field .
