the first thing you should do is to convince yourself that you are able to work well, because many people who regret trading, they always think about the benefits without thinking about the risks faced, so when faced with those risks, they feel loss and regret has been trading.
therefore I advise you to really think carefully if you want to trade so you do not feel sorry about the decision you choose.
Once you are sure, then you can search for information on the internet and ask people who are experienced in trading.
