Forex and traders

Idk why people who trade think that that's the only way people around them can make money. Not hating on them but like this guys are like a laser beam, only seeing supporting their life by just trading. I have a good job and the pay is great but mu friend keeps pressuring me to join sijui trading classes and all. Idk how to convince them that it's sort of gambling (which is true of you're open to reasoning) and si kila siku ni Sunday.
