Been doing it for a long time now, even during marriage. The top 1% of women (models, professional actresses) very rarely have STDs because their appearance is their life. They don't risk it. Though I have to be honest, my game is off recently. I may be too old for it. I enjoy raising my kids.
It's not important. The point is I like income streams as opposed to capital appreciation because it gives me time to do the things I enjoy. There was a "click" this year where the "passive" income overtook my expenses, including the kids' private schools. It's a pretty good feeling and I still own the underlyings. Capital appreciation can't compare in my opinion. Edit: it's a pretty powerful feeling knowing that if I want a special vacation, I just need to hang out the shingle for a few weeks. I'm teaching the kids to do this as well.
My way is to be a "market timer". Try to be in something when the market suggests I should, but be out/short when it suggests that.... via "Price TA". (I used to run a mutual fund market timing service as an RIA. Not a big fish by any means... had only about $60MM under management at peak. However, our results were by most measures, "spectacular"... was told may times, "sounds too good to be true". True, none-the-less. Got audited by the SEC when the local business journal highlighted me and my business... passed with flying colors, BTW.) Warren Buffet's way is to do fundamental analysis on companies. When he finds one he can justifiably conclude it's "undervalued", he buys a big chunk of it or the entire thing.... and tries to hold until the marketplace comes to the same realization. That's a great way to invest, but requires lots of time and knowledge which most market players/investors don't have or don't want to commit to.
