They are made, but it helps if you were born smart
I think innate ability is very important in determining the performance at the projects you undertake. A person good at mathematics might not be very good at cellular knowledge. It also depends on the training you get. Normally, a period of six months is more than enough for someone to specialize in a field. If you are not good at trade, you can become the best trader by exploring and practicing.
I don't think anyone is born smart, depends on each person's own efforts. Einstein was not born and then clever about mathematics, he tried and studied. Likewise with traders, you have to learn and try, if you keep trying and learning at certain times you can get even more expert
Everyone is born of equal intelligence and knowledge. It is up to an individual on how he/she would develop more techniques and learnings depending on the environment on where he/she is exposed to. Like traders or any other profession, they are learned through experience or by interest. Saying that people are born smart may reflect on their livelihood and lifestyle as they live a life full of blames.
The experience that a person face City to grow his journey in trading will make a person to be a good trader so no one will came to huge knowledge and huge experience in this field it all made with the time and interest that you have been spent here in trading so ja huge profitable traders will definitely be a huge interested person in this field.
That is definitely true. An individual becomes someone if he/she develops the right attitude based on his individual experiences and personal growth. Hard work and luck are the reason on why many people are successful on their respective field. Those are just the basic formula for success!
