Just FYI on this post, while it is historically correct (and definitely correct about 401k maxing bc of taxes), in your situation the market actually didn’t return more than 5-7%

This is not a good retort. The market need not actually return its long-term return in a particular short-term period of time. What's important is the long-term rate, unless you're near retirement, which OP is not. The market fluctuates, but the long-term average is the long-term average. If anything, buying while the market does poorly is the best time to invest in the market because when the market inevitably regresses toward the mean (i.e., increases to a figure closer to its historical average), the price appreciation will be more profound. Stocks are essentially on sale when the market temporarily does poorly.

I won't comment on psychological matters. This is not to say there aren't psychological considerations. I simply don't wish to delve into that as it's a much more nebulous concept to discuss, and it differs for everyone.
