When I was young and fresh out of college, I earned £8000 per annum and attempted to support a non-working partner and a small child. The idea of time vs money was irrelevant. I did not have enough money to live on. I would work as much as possible to get more money, and it still wasn't enough to live on. Fast forward to now where I have enough money not to bother about budgeting day to day and there is still enough…
So, time vs money is a rich persons dilemma.
It's also a monk or nun's dilemma and a motivating factor in ordination for some.
