Now is not the time for the U.S., Taiwan to poke China: NYT's Tom Friedman

I am new to the stock market. Every stock that I bought so far, I was out of luck because I bought them when they were expensive. I feel I missed on all the stock opportunities so far for the tech stocks.I believe having 75K yearly income would be a good investment so I want to plug all my savings into the stock market. I know this sounds a bit dull but I would like to know if I should learn investing or let somebody else (more capable like a FA) do it for me? Please share your thoughts. I am kind of tired of searching for a good stock to buy and loosing all the good opportunities :(
