If people says other things without putting money first, I wouldn't say they aren't saying the truth but they are not completely been honest about what motivate them. As for me, money first and that is what makes me come back again and again even the days it doesn't favour me or made loss. No trader will be happy without making money on trading, it's the money that gives us hope and another chance of coming back, some days that you don't make money, if you remember the other days you made, you wouldn't want to give up.
Another thing that motivate me apart from money is that I improved financial from trading, I don't have the millions like other people does in trading but every day that I try, it's always better than yesterday and I'm sure tomorrow is going to be better than tomorrow, so for those people that are having it hard right now, don't give up because you never even know your potential if you quit so soon. Trading is the only thing you don't have to depend on anyone.
I agree with you, making money from trading is certainly the main motivation for everyone who trades, but to get profitable results of course we must be able to do it well and correctly because it is impossible to make money without understanding well about trading, when experiencing failure of course everyone will think about not doing it again but when they remember having felt the benefits of course will correct the mistakes made and will return to trading.
It is true, we will be able to generate additional income from trading when we have been able to do it well and stopping when experiencing failure is certainly not the right choice it would be better if we continue to learn trading and correct those mistakes and also have to be very careful when trying it again and also I agree with you not to depend on anyone but we have to make our own decisions on the trades we make.
