There are many people who lost their money on trading, because trading is unpredictable job, in my opinion i need:
Method ( i must have system trading)
Money ( i must have management of money and risk)
Mind ( i must can control my emotion)
Tell me your opinions?
The three elements you mentioned are good enough in my opinion, but there is one element that you should be interested in trading that is "Strategy".
Not enough just capital, and controlling your emotions must have a reliable strategy in trading. There are several strategies you can learn and I hope you read this forum.
You can develop your strategies as definitely you can learn more along the way and your experience is your best teacher.
However, if you do not have enough money to be use in your venture in trading, everything you work for will become useless, you need
money to gamble and if you are successful that is when you will be satisfied and that happened because you risk your money.
Just like they say, we can only know if we are good if we are willing to risk our money on the strategies we believe will work for us.
