Basically what EviLore said, but I'll explain index funds in super boiled down way. It is really easy to get into and you don't have to understand stocks, but just trust that the market will continue growing (just as it has for the last 40 years), and so naturally there is still some risk should another great depression event happen. Still, with apps like Robinhood making it dead easy to buy stocks individually, I think we will continue seeing the stock market grow as these apps game-ify it and make it way less intimidating. I would not recommend trying to pick stocks yourself or having a broker person pick them for you, I think the statistics ironically show that index funds do a better job because they scatter their eggs far and wide into different industries instead of placing them into one or few stocks in the same. You'll have bad years and great years, but they average out to about 10% - 12% yearly which is pretty damn good.
Index funds.
How do you double your money in 7 to 8 years?
Compound interest. Just think compound interest when you think of index funds.
In my super simple example below, you'll put in $5000 and get 10% return every year (tax will eat a % of that so maybe 7% to 8%, but for simplicity sake):
- 1st year: $5000 * 10% = $500 gained; $5000 + $500 = $5500.
- 2nd year: $5500 * 10% = $550 gained; $5500 + $550 = $6050.
- 3rd year: $6050 * 10% = $605 gained; $6050 + $605 = $6700.
- 4th year: $6700 * 10% = $670 gained; $6700 + $670 = $7370.
- 5th year: $7370 * 10% = $737 gained; $7370 + $737 = $8,107.
- 6th year: $8107 * 10% = $810 gained; $8107 + $810 = $8917.
- 7th year: $8917 * 10% = $891 gained; $8917 + $891 = $9808.
In this example I used a flat 10% every year. In 7 years you have nearly doubled the amount of your initial investment
without investing anymore. It basically continues snowballing so long as the stock market grows. In chart form (my math might be messed up above but the amount is similar):
You can play around with it here:

So how do people get into this? Well, seeing all the graphs, charts, and investment lingo, a lot of people are intimidated to research it and go to a local investment broker who will get you set up, but they take a % cut of your profit (that's how they earn their living) and thus your earnings are lowered.
A broker doesn't have to be a person, though, it can be an institution. Vanguard has index funds with minimal fees (0.10% to 0.15% I think). That means you get to keep a much larger chunk of it. Just go to their website, create an account for free, and transfer money from your bank into it. Once transferred, Google how to put your money into a Vanguard index fund.

As for other forms of investment, I think I'd get stressed with real estate right now. I think not being able to sell the asset immediately like stocks makes it harder for me to swallow. Maybe when I am older.

I'm not an investment guru so don't blame me if the stock market crashes as soon as you put your money into it.
