Experience will make you realize the things you've learned that cannot be easily taught, or completely cannot be taught.
IMO, one of the things that cannot be taught is the perspective of trading which is also correlate with the trading psychology. Consistent small gains is better than being greedy and look to maximize the trade profit which usually leads to a loss. That's what patience means in trading, which everyone talks about but only few could apply in a real situation.
That feels of greed is pretty common specially to those people who do just recently started up and they do able to see from others on making big profits.They do picture out that
they can do the same thing until they do able to have some taste on what reality looks like.
Nothing can really teach us but only gaining it thru experience.From theory to emotion handling, you will all learn this along the way. Becoming successful will depend if you do accept
and learn from those lessons.
Having a strong mind+ determination +unwavering goal setting will really lead you into a good path.
