Which method(s) should I use?

Many of us including me are always wondering which is the best method to invest/trade? Which books should I read to learn more? Which guru's seminars should I attend so that I can invest/trade better? Which blogs should I visit?

SO the QUESTION is:

Which method should I use? FA? TA? value investing? value growth investing? dividend investing?

Actually regarding of which methods you use, just make sure it suit you and it works!!

How to know that it suit you? -> make sure you can sleep well every night without worrying about the buy/sell
How to know if it works? -> like what cw always said, measure your performance!

As a summary: 

不管是黑猫还是白猫，能够捉老鼠的就是好猫！
