I am pretty familiar, which is why it is overwhelming.How familiar are you & how investments work? If you aren't too familiar, then I'd suggest you'd sit down with an adviser.
When you sit down with one, make sure they have YOUR best interests in hand. If they do more talking than listening, then yes, be a lil suspect. If you tell them what you're looking for, they give some suggestions & you feel comfortable with it, then it's more likely you have somebody who has your best interest in mind.
Financial advisers give themselves a bad name when looking for the highest commission or fees. The referrals are more powerful than one client & one fee. You do great for a client, they will refer you. Now, there will be times you may lose some money, that's the risk you have to take with investing. Just make sure you ask the financial adviser what they did for their clients during the Great Recession.
I don't think body language is a great way to rate a financial advisor. They can be for my best interests and still suck.
