REITs are taxed, by the way, as if you were making any dividends as regular income, UNLESS they're in a non-taxable account.
Yeah, boring investment is the best. As far as stock picking, you are at least looking at the most boring stock picks!
I have about what you suggested in O, and I'm fine with that. I get a bit of pride out of owning and following a few companies, but it's not the way to retire. I aim to have roughly 10-25% of my portfolio in specific stocks (a basket of about 25 I picked out) and the rest in VTI and VXUS.
Individual stock perks, if you love boats, could use a car insurance discount, want coffee coupons, etc. could also be factors in stock picking in very small amounts.
Berkshire offers the Omaha conference and Geico discount (the most Mustachian perk)
Royal Caribbean offers cheaper cruises (but you're not going on cruises, right...? Haha)
Ford offers cheaper new cars (which you also shouldn't be doing!)
McDonalds and Starbucks occasionally send coupons (hell no and ok respectively)
