If you want the low effort, safe returns, then just invest in an index fund. These are specifically funds that invest in all the major stocks. It's effectively the simple way to get an already diversified portfolio that's as "safe" as the stock market can be. The safety means growth is slow, but generally consistent and you're predicted from massive downswings. Obviously if the whole market drops, your stocks suffers, but that's true if you're not invested in indexes too.

If your goal is to simply make your money grow well over the long term, do that.

If you want to get into stocks to make it big quick (ie in years rather than decades), you'll need to do a lot more reading and studying, there is no quick answer because there's lots of small answers and they're all inherent with their own risks. If you don't know stocks at all, you will genuinely want to study the basics before trying to decide what you're comfortable with. Just be aware there is no true "it just werks" way for making it big quick. There's always a risk.
