From the Bogleheads® investment philosophy:

I recommend you take the time to read the materials published on the site and work to understand it. Some of these lessons I understood right away, some have taken me years to learn, and some I'm still working through.

The challenge is fighting your own impulses. Am I doing the right thing? Should I be doing something different? X just had huge returns I should have been invested in that.

Here’s the thing, it’s always easy to feel smart when you’re reading history, it’s an entirely different thing to live through it.

I’ll help you with this as much as I can. And if I’m not around don’t worry. The community is there to help you.
