This is why it's important to have other sources of income. Trading is like any other things in which not all people can be good at but we must not afraid to try it. There are so many learning materials online that we can use. Some are hiring a mentor to make things easier. In our first attempt, we can use play money first. When using real money, we can start with a small amount. If things don't run well after several trades. That must be the time to move on.
You can try to get rich trading, but it's even harder than starting a small business, I'm talking about successful trading, that can brings you income. You can learn as much as you want and from anyone, but it will not be easy. And advice with a demo account is not a good idea at all, because I think that this is the same as playing monopoly, yes it can be interesting, but it has nothing to do with real trading and trading experience.
