The best practice is to learn from your mistakes instead of repeating the same thing and putting blame on others for the same.
The better than best practice of learning from our own experience is learning from others' mistakes. This way we are able to acquire knowledge without personal losses. I believe it is the sweetest thing in gambling, being able to amass experience through the experience of others.
Learning from other people's mistakes or gaining experience from other people's experiences cannot guarantee that we will be better, especially in the gambling industry where there are many temptations and always haunted by curiosity.
In my opinion, a person can learn and really understand everything he does with his own mistakes because from there a person can think and be more careful so that in the future he will not repeat the same mistake again.
After all, by having our own experience we can have more knowledge that we really master not only from other people's stories but we do it ourselves.
