Whole life insurance as an investment vehicle

My 1 experience with a financial advisor 18 years ago. I did my high school senior project on investing. So my “mentor” was this financial advisor. I had 5k from my grandmothers to invest in (my great grandmother has mutual funds for all the grandkids so I cashed mine out and my grandma also threw in $1,000 for me)

Anyway.

His can’t miss these are about to be the next big thing picks were Nokia and Pioneer energy services. So Nokia only ever went downhill, I bought I think around $16 and sold at $5 some years later. Pioneer it actually had tripled at one point to $18 then a year later it was $2 then they went bankrupt so bye bye to that money.

I was really into computers back then, I had built my own and talked to him about how everyone in gaming was using Nvidia GeForce graphics cards. He has no interest in it. I can still hear his whiny voice saying how computer industry moves so fast and there will always be some new better faster thing on the market so that would be bad to invest in. And how Nokia was going to rule the cell phone market for years and years.

In 2005, I was advised by a group of real estate investors. One who says he owns 50 different properties with many partners. He advised if I do not have money for investing, I should use my identity for prospect investors to use to purchase property and I get a small share. At the time, people made lot of money and different kind of real estate financial schemes.

Definitely it is a bad advice because if the investors default the loans, you are ultimately responsible for the loans and the properties are under the water.

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%.
