How the hell does everyone keep up??

I'm reasonably new to investing, having just reached my 1 year anniversary in the market in mid-July. I'm a college student, but I've spent years building my savings in order to try and get out there with as much cash as possible and do something productive with it. I cannot for the life of me find good places to throw said cash until long after the hype train has expired, 52-week highs have been reached, and the party is over. I'm by no means looking for short squeezes, and I know that even the most reasonable timeline to make a good return is measured in years, maybe even decades, but I have no clue how to find good stocks. Here's what I have done over the past year:

1. Invested in things I know/believe in. I currently hold 4 common stock positions. Intel, because I use their computer hardware, know a fair bit about the company, and have a reasonable degree of confidence in their future plans. Cisco, because everywhere I go I see their Wifi services, at school, at work, at my friend's house, etc. Qualcomm, because similarly to Intel, I use their technology in my day-to-day life, they have reasonable dividend payouts, and seem to be a sturdy long-term holding. AT&T, because I made a mistake and am too stubborn to admit it.
2. Started doing as much research as possible online. I look here, I look in the news, I look at the articles Fidelity offers when I look at common stocks, and I talk to all my connections in various industries about how they think their fields will perform.
3. Listing to podcasts like Wallstreet Breakfast and Marketplace.

I feel like I'm doing everything to cover my bases, and still get serious cases of FOMO every time I turn around. There so much noise out there between wanna-be gurus, real gurus who all seem to say different shit at the same time, and an overabundance of clickbait articles. How the hell do you guys keep up with the market and manage to make quality investments, whether over the short term or the long term?

I do also have a position in a S&P 500 Index Fund. I might be dumb but I'm not stupid, if nothing else I have that to fall back on.
