If you want to pick stocks, and not just use a roboadvisor like betterment or wealthfront you have to understand that the market does not always go up.
This means you have to have a bear market strategy and know when to switch modes from bull to bear by watching and deeply understanding the federal reserve. Otherwise, just give up and use a roboadvisor.
In my case, I sold my tech portfolio when it was clear we were in a bear market when the war broke out and inflation was roaring. There's a reason people spend crazy amounts of time analyzing the fed. When they start raising rates a lot, like 75 basis points, the market WILL crash.
I then started playing around with swing trading energy and monkeypox stocks and options and I'm now a little ahead of break even for the year. Generally government spending (monkeypox) and whatever is driving the inflation (energy) does well in an inflationary depression, which is what we're in. You have to watch the news though to see if monkeypox is a dud or if opec is going to throw a tantrum in response to world events, like when probably the U.S starts destroying energy infrastructure.
Sure, swing trading is short term capital gains, but the key to investing is DON'T LOSE MONEY. You can only use $3000 in losses a year, so losing money in the stock market is double bad.
I will eventually become a bull again when the fed decides to start lowering rates. Permabears are just as big of stock market losers as permabulls.
