Everyone can learn and try to trade, but is it for everyone especially for those who thinking that trading is a some sort of quick money making scheme then it's not for them. You won't get anything if you are new unless it's beginner luck. If you want to go into marathon way and want to learn and experience the worst trading feel with losses then it's for you with every losses make you stronger and want to learn more and more.
Otherwise, if you are a person that is easily demotivated once something bad happens then you better stay away.
Because success never comes too easy in trading, you will first commit mistakes and suffer losses before you reach it and if you are impatient, this will be no longer for them. That is why they are easily demotivated because they are not thinking negatively and hopelessly as they don't understand how this thing works. Trading is not just knowing how to trade but also how to control ourselves (emotionally), and most of all, mindset. However, it is still need for us to accept that not all are for trading, quitting is an option if we really know we can't do it anymore rather than forcing ourselves which will still end up losing more.
