You're Quite Right, You Can "Do It Yourself"
However, investment is about numbers. The various scenarios I described above can be expressed as mathematical formulae that assist in the optimization of strategies responsive to individual needs. Making use of such tools helps build investment portfolios responsive to current needs and long- and short-term planning.
Degrees of risk tolerance can be quantified, and various investment vehicles then filtered for such traits. A stock I might choose to purchase because of its volitility and volume metrics might be precisely the one you should avoid based upon your own situation.
Gut level investing isn't investing (I'm not saying you do this), it's gambling, and the house has the odds in its favor. Every dollar someone loses goes somewhere..., to the person on the right side of the trade. As the saying goes: the financial markets are a parimutual system for redistributing capital to its rightful owner..., usually the person with better information.
Emotion is an important factor here. We are all quite emotional about our money. It's the source of both pleasure and pain. It affects our relationships, our love life. It's almost impossible to think of our hard earned pile as, simply, inventory. One reason to consult a financial advisor is to get the pragmatic, unemotional viewpoint of someone who deals with such questions every day.
It's also important, I think, to clearly identify the role of a securities broker. A broker is a salesman. Having studied for and passed the NASD Series 7 and 63 exams, a broker is trained to sell investments and then execute trades. A broker is not trained as a financial advisor. I am not demeaning brokers. I know good, honest hardworking brokers who care a lot about their clients' wellbeing. But, their role is limited, not only by training but also by SEC regulation.
Shops like Fidelity, Goldman, Advest, Edwards, etc, are reputable firms with justly deserved reputations. A reality of the securities business is, however, that the regulatory structure it operates under is so arcane and complex that even the most dilligent and honest of them occassionally is in violation of something (it's a lot like the FARS).
I'm not suggesting that people ignore these and other fine companies. What I'm suggesting is that one make use of a skill set that, possibly, you've overlooked or perhaps weren't aware of in making investment plans.
A Chartered Financial Analyst is not a Financial Planner in the sense you are thinking of. The training is more along the lines of Financial Engineering. A CFA does not sell products. A CFA sells knowledge. The majority of CFAs work for investment banks doing what is known as fundamental analysis of publically traded securities, whether they be fixed income, stocks, CMOs, options, etc. One branch of the work is involved in Private Wealth Management. It's a highly mathematical discipline, and has sometimes been called "financial forensics," when referring to the analysis of SEC filings made by a company. This is a skill set unknown to a traditional Financial Planner.
The skills I have aquired in earning the CFA Level 1 (equivalent of a PPL in this field except that it took a year and 500 hours of study), has enabled me to perform rational analyses on individual stock trades at a level I would never be able to accomplish without the knowledge. Have I benefited from this? Yes.
Could anyone benefit from talking to a Chartered Financial Analyst about their investment strategy? In my opinion, yes. Thus, I suggest taking a look at this section of the web site:

No matter what, I hope everyone makes money. Of course, that's impossible, because for someone to make a dollar it has to come from someone else. ;~)
