As a relatively new trader and still looking to develop and improve my skills every day, the advice I can give is that you must find a trading system/methodology that works for your personality and lifestyle. For example: if you have a fulltime job, trying to become a day trader may not work, and you may be setting yourself up for failure.
Secondly, you have to put the time in to understand, develop and fine-tune your system. This isn’t a get rich quick overnight scheme. Its a long term prospect that will allow you to trade for decades into the future if you put the work in now.
Finally, I believe that with solid money management and trade psychology, you can pass the trading evaluation with CTI. Being able to manage your risk appropriately will allow you to continue to trade into the future, but also demonstrates that preserving your trading capital shows discipline and focus and is the key to success in trading.
