You're probably already doing this but trade, with a live account, start small, with small lots, a micro lot. Remember this is a marathon, also do what every course, book, forum, web site and everything you've ever read is telling you. Start with a trading plan, have a methodology for trading, keep records for reviewing, and do the same thing over and over again.
You're trying to create consistency, and with consistency you will be profitable. All the information you need is here with babypips, but it never hurts to study more, don't think you need to buy a course, you just need to find a trading method right for you.
