Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error. For more on this topic, see Cost Segregation Studies.

Frugal living does not mean deprivation. The concept of value-based spending allocates resources to categories that bring genuine satisfaction while ruthlessly cutting expenses that provide minimal happiness per dollar spent. For more on this topic, see Sequence of Returns Risk.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
