I came here, like most, with the dream of making a good life from trading. I arrived with a bubble that the senior members were quick to burst - which I am glad they did.
This industry is full of dreams and promises, many of which are not accurate. And even some of the things that are possible, may not be attainable by you or I, merely because of what makes us who we are.
Can I promise you riches? Of course not, nobody can.
Can I promise you a challenge? You bet!
The best advice I could give you is to bring it all back to basics. Keep it simple. Learning to trade can be overwhelming, but stick at it, and keep things simple. Ask questions, listen to what you are being told, but as timsk said, take it all with a pinch of salt.
I was recommended this by a member on here when I first started, and I now recommend it to you.
It's a free trading course -

Also, I found it helps to listen to and study successful people. Some are not even traders/investors.
Being a student of the market will really help you... understand what money is, how it came about, understand how markets work... how commodity markets differ from currency and stock markets.
I am not going to tell you that demo trading is wrong. What I will say is that I am glad I quickly moved to a micro live account as having some skin in the game helped me focus. My broker is Oanda, they will let you deposit $5 if you wish. I am not exactly recommending them as a broker... I'm sure there are better... but it did the job for me.
This is an amazing journey! Frustrating, but rewarding depending on what sort of person you are.
** Full disclosure: I am not a profitable trader. I am just recently getting back to break-even after losing 60% when I started in May '17
