Munger argues that adults should generally spend less than they earn and preserve part of their income for the future. His emphasis on deferred gratification reflects the idea that giving up some consumption today can create greater financial security and opportunity later.

The quote also links saving with discipline. Immediate spending can be attractive, but consistently choosing longer-term benefits may allow capital to accumulate and provide greater flexibility over time. The principle is especially relevant where savings can be invested or used to absorb unexpected costs.

More broadly, Munger presents financial restraint as a practical habit rather than a complex strategy. His language is blunt, but the underlying point is that sustainable wealth often depends on ordinary behaviour repeated over long periods: avoiding unnecessary expenditure, preserving resources and accepting that some rewards are worth waiting for.
