Do you really think it's easy to be trading and running your normal job at the same time?? Hehe...
Trading requires a huge amount of time and concentration. I believe jobs over your country would atleast run for 6 hours, how do you cope ?? I use to ask questions atimes cus ion really understand why things are being done that way ... - why should I stress myself a whole month just to get paid in peanut when I could simply get that in barely one week or so??... It was said - "that if a man chases two squirrel at the same time, he ends up getting none at the end".
So you're trying to advice him to quit his teaching job and focus on trading. By quiting his teaching job he's giving up on the kids he used to teach to focus on himself. if you ask me I'll call that selfishness. Life isn't about the money that we were able to make but the lifes we were able to impact while we were on earth because when you finally depart this world, it's the memories that stays with us and not the money you were able to gather while you were here. They'll just be passed on to your next of kin that'll rubbish the money as we see with today's youths living unnecessary expensive lifestyle because they didn't work for their money.
Trading doesn't need all your time and concentration and it mustn't be a full time job. Majority of traders we have are part time traders. They're not actively on the desktop screen minoring every candle stick. You can complete your trades for the day in matters of hours and carryon with other matters of life so the teacher must not basically quit unless she or he doesn't love what he's doing by impacting knowledge into the younger generation then she can quit and focused all her attention of looking for money through trading.
