I think the goal should be making it source of income instead of trying to make it a way to have a better life because that would only out the trader under a lot of pressure. Most people get into trading having too much hopes on it, there's nothing wrong with being optimistic but people must understand that trading also has it's down sides, not everything can be under that control of the trader
Having a source of income is also the same as having a better life because when you can afford your needs then you have a better life so actually is not mostly with big account of money that's a better life but unfortunately even if it should be considered or taking as the means how would everybody be able to take a regular income from it when the complexity is above a lot of people. Positive belief of success doesn't really assured success if the person doesn't have determination because a person could be saying that they would definitely succeed in trading when they're not ready to do the necessary things some others did to be able to see a little positive trading for themselves.
