Personally I was 100% equities until late in my 40s. I don't really see anything wrong with that or close to it while you're still working.
I kept asking my "seasoned professional" FA if I should have some bonds in the mix? He kept telling me, basically, "bonds are for wussies". I was disagreeing with him in other investment decisions too, which helped me on the way to DIY. Of course 2008 helped that decision too. I lucked into having gone to mostly cash before the big drop (sold a bunch just before to build a big new house, and didn't immediately reinvest when we sold the old one), but then got stuck in the "when to get back in" dilemma. I've been DCA nibbling back in all during the rising market. That taught me good hard lessons too.
I'm still around 65/35, just getting ready to turn 60. I think/hope I'm comfortable enough with that to be able to hold on during another big drop. I guess we'll see.
