most people are lazy but greedy at the same time which is the reason they will never get time to develop their skills but going for trading how they are gambling and keep gambling for easy money.
If you're having only one emotional problem then probably you can come out of it but when you're having two problems which are related to your emotional failures then probably you will never find any appropriate solutions to recover from it. I mean being greedy and being lazy cannot be a simple emotional failures for any trader or gambler. They must need more attention and time to recover from it so that they could find opportunities to make use of trading and by leaving off gambling.
When you're not good in the emotion control then definitely you will get addicted even with trading. But unfortunately most people are thinking only gambling is addictive.
