How I wish it had only taken me 3 years to turn net positive. I guess I'm the dull bulb around here.
No augment there

FWIW, I think you have a need to be right and that's probably what slowed your assent to trading success. Meanwhile.....some of us turned the corner within 3 months, and completed our first double within 6. I was just more interested in making money. Could care less about being right!
What does it take? Discipline, attitude, absolute expectancy, hard work, and determination, helps to have a model to work with, to study under other experienced traders, OH yeah......did I mention you need to be an optimist?
20k is enough to get it done. Especially since your cost of living is so low. I started out with 25k and had one years worth of expenses, and haven't looked back since.
Don't let the naysayers bring you down, this place is notorious for that, instead choose to focus only on what information you can use and will help you, forget about the rest.
Final tip, don't trade any larger then a one lot until you know you can make money. If you make money 4 out of 5 days, then add some size. Repeat the process. Have an absolute stop loss for the first trade of the day, and a daily max stop that you will stick too! WHen you have a bad day.....study it, learn from it, ask yourself how can I use that information to make money in the future? The next day, next trade, try to make it a winner. This has a tremendous effect on your psychology, it let's you know that bad day was just an anomaly, that going forward you can make money.
Good luck....hope to see you in the winners circle!
