Assuming that only 10% had succeeded in trading but I don't think they'll get into an easy trading history or being an instant millionaire. For this 10% out of thousand individuals who tried in this, it for sure they are able to reach their goal but it takes years.
Definitely, it is our decision to take the risk or not, to weaken and quiet when suffered losses and difficulties? These things will give us an excuse of not achieving our goal and aiming to become rich is just a dream at all.
For I am into trading, I don't aim that high. What I ask for and working hard is to make a profit in every trade I make. Well, that be close to that soon if I continue doing this.
Those 10% not succeed because they are the only ones who are good at trading, they succeed because they are the only ones who want to succeed and realize what it takes. Those 90% include some people who would be great traders but they fail to become one because they can't wait to make some money, if they wait a lot longer and they work hard and long hours for years they would become one of those 10% as well but they fail because they want to get rich right now.
If you know what it takes to be a good trader, if you are willing to study, if you are willing to learn, if you are willing to practice, if you are willing to trade for 1-2 years gaining experience with lower amounts, you will get into that 10%, but you have to do all of these very properly without getting any shortcuts or wanting any quick returns, if you can do this you will become one of those 10% that profit.
