What is front loading sacrifice?

"Front loading sacrifice" refers to the concept of making significant efforts and sacrifices early in a process to benefit from easier and better conditions in the future. Brad Barrett explains this as investing time and energy upfront so that future days are less cumbersome and offer more freedom and choices. This concept is often applied in the context of achieving financial independence, where, for example, saving a substantial portion of one's income early in life can lead to an easier financial situation later 1.
