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.

Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description.
