I agree your portfolio is appealing for those reasons, and would be especially more appealing if you had $2M+ (don't think you're there yet though?)The expected performance loss with my 30% equity allocation is only about 0.5% to 1% CAGR versus 60/40 so I'm not too worried that I'm ruining my life by not taking more risk.
I also suspect that I will end up with superior long term returns to some more aggressive investors because of emotional reactions they will have during bear markets. I've already seen this in real life. I'm already doing better than some of my friends with higher equity allocations.
Advisors and books never account for those real world effects.
But also that without the backstop of a paid off primary residence, your preferred asset allocation applied to a smallish portfolio has inadequate inflation protection, IMO.
