Trading for a living is possible.
I would suggest that you use the following structure as a guide:
1. Decide what type of trader you would like to become:
a. Day trader or scalper (trade instruments for a few hours a day. Usually, two to six hours).
b. Swing Trader (trade/hold instruments for a few days. Usually, three days to a week).
c. Positions Trader (trade/hold instruments for weeks to months. Usually from a couple of weeks
to a year).
2. Knowlegde is important. However, the key to success in the Forex Markets is Discipline!
a. Yes, it is important that you understand your indicators, charting, etc. It's actually essential.
Nevertheless, structured behavior (discipline) is the HOW YOU WILL ACCOMPLISH YOUR
GOALS.
b. You need to assess your emotional state and set up a realistic trading plan. More importantly,
the trading plan must be followed rigurously.
3. Your trading must be unemotional as possible.
a. Greed- You made some money...now, you want to make some more (stay away from this trap
and stick to the plan).
b. Fear- Selling or covering your positions prematurely will cut your bottom line (reduce profits).
Bottom line: Know when to get in and know when to get out (that's when knowledge comes in).
4. Prepare yourself
a. Review charts for a while before entering a trade.
5. Other stuff
a. You must sleep well. Don't trade while you are tired.
b. Don't enter a trade if you are not sure of it.
c. Constantly update your charts as time goes (look for new patterns forming by price action, like,
triangles, wedges, etc).
d. Believe in yourself.
e. Be patient. Profits do come in; as long as, you do what you are supposed to do!
f. Take time off from trading as often as possible (vacation), and avoid over trading. With the
right system, you can make a living only with few trades a day (1-5). Trading can drain you!
g. Find a trading partner, so you are not so alone since trading is usually a lonely task.
You will have to do more research on these points in order to get a clearer picture of what you need to do in order to accomplish your goals. Nevertheless, keep in mind that the key for success is Discipline!
