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 Backdoor Roth IRA.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
