As a successful trader, you should focus on the process instead of the money, because the process is the must important thing for you to get more experience in it, and once you are focus it you never lose your money in trading, so as successful trader you must always be fucus on the process of your trading, for you to get a good profit.
To certain extent which is possible but if the trader isn't making any progress or can't afford to sustain with the loss then better quit instead of getting into debt, it's okay to accept if something doesn't go in the way you expected and it's not going to make any less of you.
Apart from that you nailed it and this is what a trader should do to gain experience which is the process of becoming a successful trader, not just learning technical analysis or learning trading courses but it's all about managing the situations.
