Some thoughts about trading.
In trading, it is not important (in my opinion) to know everything.
You just have to learn (or listen) and find in your own way how the markets really works and from there implement or practice in actual trading what ideas you had.
It takes time, but if you persist and have the goals to succeed, nothing is impossible.
There are many ways to get involve in the market, you just have to find simple idea(s) that works for you.
In fact, one idea is enough, you just have to master it and tweak it as you go along.
But you have to do a lot of reading and educate yourself about the market, but that will come easily while you are in the market.
Skills is the most important, practicing the skills and knowledge about the market is the key to successful trading.
And based from studies and as mentioned from Malcolm Gladwell's "Outliers" book, it takes 10,000 hours of practicing your skills to master your field.
That's why commitment and patience is important in any endeavor.
