Am new here, and with my little knowledge am sure a good trader should have all the patience he/she can get.
Patience is needed, you have to be patience in terms of lost, trading is not always about benefits at all times, you will always run into lost a lot and that might trigger you to want to back out, but with patience you can scale through.
You are right about have patience because a lot people lack it as easy as it looks that is how hard it is to keep because you might, and even with you been new you are right about the statement you made, trading is about money because the money is what will actually encourage you to be able to want to do more and that is why when you make profit you are happy you want to do more and when you are sad you feel like quitting, the emotion will determine the direction you will go when it comes to trading and that is why emotional control is very important.
Another thing is discipline, by disciplining yourself you will have the enablement to purse a goal you have set, and it will help you to be forced at all times.
Trading is a lose and gain thing if you aren't making profit you have to quit.
Decipline to avoid spending to much of your profit is also very important and setting goals thay no matter how difficult you will be able to archive it, a lot of things matters when it comes to trading the lose and gain you are talking about have to be taking seriously.
