Financial investing and trading can be said to be both difficult and easy.
It's easy for disciplined people to "repeat" continuously to the point of mastery, creating unconscious habits of forgetting...
And it is difficult for those who are not disciplined and trade frequently indiscriminately...
If you know discipline, know how to manage capital, know when to enter the market according to your trading mindset/system and practice them masterfully, you will find them easy...
If you do not have stability and consistency in each investment, each time you enter an order... then that instability will be reflected in the trading results... automatically your mind will I find this a difficult job...
Difficult or easy depends on each of us's MIND.
