The true meaning of life is to plant trees, under whose shade you do not expect to sit. (Nelson Henderson, 19th century athlete)
If we’re interested in landscaping in an age of impatience, such as today, we’d want to plant fast-growing trees, so we can enjoy them in a few short years. Henderson suggests that we can make a more significant contribution for a meaningful life if we plant slow-growing but long-lasting trees. That would be thinking of the future of others rather than our own personal enjoyment.
Don’t look out only for your own interests, but take an interest in others, too (Philippians 2:4).
