A wise man once said : "teach a man and he will never learn", and this is the problem of most people. They tend to think that in order to get knowledge they must have a perfect teacher, the perfect book or the perfect opportunity...so they end up waiting their whole lives for this magical element, which will never come to them.
Teachers exist to show you the right path, to make you able to continue the walk by yourself. If you think it is up to a teacher to make you succeed in life, you are absolutely wrong, because the journey is yours, it is your duty to fight and struggle for information and knowledge, don't wait for someone's else sympathy, no one is gonna help you, because we live in world where knowledge equals power. People are too egoist to share this power, yet thanks GOD, in this same world some great people make awesome books and articles to help anyone learn anywhere and anytime. Gone those days when people in order to learn, they had to travel faraway to become disciples of some weird temple's masters, today just via one click the world is yours.
The second thing to know, is that back in the day when people used to go to temples to seek for knowledge, rare does who went back to their homes not being a master too, because the knowledge they get is not a bunch of sentences written in a book or whatever. They used to make of that field a way of living, they eat it, they breath it, they dream of it and mostly they apply it, and that was the most effective way of learning. Unfortunately, today most student at schools don't even know why they learn what they learn Sometimes it is due to the educational systems, and sometimes because they were obliged to choose that field.
The process of learning and getting this ultimate form of power which is knowledge can be described as following: Once you find your true passion and inclination, start reading and getting information about it anyhow, because at the beginning all we have about a field are prejudgments, we are outsiders. The second to do is, to find a way to apply this knowledge in our daily life. By applying you learn more quickly and effectively. The third phase, is what Robert Greene call Mastery, the ultimate level which you can reach only by getting involved and practicing over and over.
Keep in mind that the process of learning and mastering needs time, courage and stamina. It is simple but not easy, most people give quickly so they never reach the ultimate power, don't be like them, be special, because you are unique and you are gonna be successful.
