Education is one the best to guide you before entering the trading market, if you have a friend who has experience enough to teach you or to guide you before entering the trading market will be great. Also prepare some money that you can afford to lose before starting trading it will help you to prevent any emotion burst 
I think it's better to have that mentor of yours that you know personally. So the chance of fooling and shilling you is quite low and you have someone to go if you don't know what to do. They're likely more honest than those courses and teachers that you might find online. There's the integrity that's very important to know for those type of people because once they fool you, you'll never going back to them and you're already aware of what type of people they are when someone approaches them and asks for help.
