Frugality and Financial Margin

When does being frugal reflect the need for a wider financial margin vs overall wise money management?

When the money that I have saved from being overly mindful ultimately came by my poor use of time in the pursuit of the savings. Essentially, I may have some short-term gain in ROI for money, but not for my time.

When frugality leads to my better use of time as well as save me money, then I’m on to something worthwhile in the long-term.
