“Someone’s sitting in the shade today because someone planted a tree a long time ago.”
Who said it: Warren Buffet, founder of Berkshire Hathaway
This quote means that we have all been helped by people in the past—even if we never knew them. Someone before us did something which helps us now. The quote uses the metaphor of planting a tree to explain this concept.
When a person planted a seed, they could not see the beautiful tree it would become, nor the people who would sit in its refreshing shade. But over many years, the seed grew into a big tree that others can enjoy. Likewise, the things we do today could help someone else in the future.
