Every trader started from being a newbie so there's absolutely nothing wrong with being a newbie.
You'd just have to start somewhere and that somewhere is gathering all necessary skills and knowledge required in trading. Digest knowledge on this forum as you'll find many discussions to that effect.
Secondly, although most people recommend demo account, I'd say you start trading with a little amount, one you can afford to lose. Many of those who use demo account get complacent about trading as they do not lose whatever way the market goes. However, if you do have something to lose, you buckle up to try to read the market well.
Thirdly, have a trading strategy that works for you. There are loads of strategies out there. Choose the one that best suits you.
