Having been trading for years, i can tell you why this is still the best job ever.
You do not need to answer to anyone but yourself. If you screw up, your income for that month will be affected. Hence you need to be very disciplined. As long as you are disciplined, you know what you are doing, you can earn a decent income. You do not need to be treated like a slave at work, working long hours with little pay.
Since we trade longer term charts, we do not need to stay in front of the computer all the time. We do monitor our trades via mobile and will check for trade setups from time to time. The rest of the time, we spend it on doing something we like.
Exponential income growth
You are able to grow your income exponentially since you can compound it. If you trade well in the long run, starting with $10,000 and taking 1% risk on each trade, someday, with a $100,000, your 1% risk will be larger, your profit will be greater too. But, it is still solid risk and money management since you only risk 1% per trade.
