Whole life insurance as an investment vehicle

Some idiot financial advisor came to my workplace circa 2006 advising everyone to take zero-downpayment, interest-only mortgages, which were widely available at the time and were what fueled the housing bubble.

Then use the proceeds to buy life insurance as an investment.

I recall asking him, what happens when the interest-only period expires and you're required to start paying principal? "Oh, don't worry, you can always refinance into another interest-only loan. "Obviously I did not follow his advice, and we all know how the real estate market ended up after the 2008 crash. (I ended up buying my house in 2012.)

Put it this way, have you ever been to a circus? You have! Well, remember those people who made you laugh? Finance advisers can also do this. But they can also make you cry. Here’s a funny story—true as well.

We had a clown, visited us as they do for many years, charging us fees, etc. Also, fees that were not revealed to us, which we discovered later. Well, after 13 years of having him sponge off us, we realized he had F.C.ED us, big style. He said the investments were not taxable as they were a specific type of investment.

Well, we realized these were taxable when we questioned him, asking, "Why did you set these investments if they are taxable?" He ran away and left us with a tax bill of 13 years, plus interest.

People will say, "Why did you not make your own enquiries into what is taxable and what is not?" Well, the answer to that is because we were paying a professional.

Well, it cost us dearly, so make sure it doesn’t happen to you. Leave the clowns in the circus!

I am 27 years old and recently inherited about $700,000. My family has a financial advisor through a more prominent firm, but I can not trust the guy. He is charging +2% fee on our total sum. He got a lot of customers, so I feel like he does not have enough time/energy to focus on my wealth.

I have been studying/reading and thinking about doing it by myself through Vanguard's index funds. I'm thinking put majority of my money in couple index funds and let it sit for years without making adjustments. However, I am pretty scared that I'm going to blow all my money.

Some say I should hire a financial advisor, but it seems like FA are all trying to do whatever is in THEIR best interest (although they say that they will be my fiduciary).

Edit: I'm sorry. I don't think I was clear regrading the fee he is charging us. 2% is one time fee as long as I leave it in that designated mutual fund. What I meant by total sum is $ I will put into a mutual fund and after that i guess there are some "hidden" fees. I guess the fee is set by each mutual fund company and he gets a little portion of that 2%.
