I think one of the most beautiful things about our FREE MARKETS is the diversity and depths they encompass. If you want ACTION you can get it however you desire. There's a flavor out there for everyone, sort of like the world as a whole and there are soooo many different ways to be successful and really make money.
The one thing I have found, and to me it's my Holy Grail of investing/trading, and remarkably it has nothing to do with T/A or indicators or systems, but rather lies within us as a person/entity:
Man, know thyself.
It's that easy to say, but that hard to achieve. Being honest with yourself and "finding" yourself are the keys, in my opinion, to being successful. This means it may take some very long periods of time finding their trading/investing style, while others will have many over a long period of time. Some may be successful at many but only settle on the one they are comfortable with, but the key is to keep at it, keep learning and practicing.
Success is out there in many different forms and by many different means, you just have to discover yourself first in order to maximize the success.
God I love the markets and those that comprise them, trade on!
