Bird Quote by Yuval Noah Harari
““Eagles, for example, identify thermal columns rising from the ground, spread their giant wings and allow the hot air to lift them upwards. Yet eagles cannot control the location of the columns, and their maximum carrying capacity is strictly proportional to their wingspan.””
About This Quote
Source Book: Homo Deus by Yuval Noah Harari, 2015
Eagles use rising warm air to soar, but they cannot choose where the currents appear, and their lift depends on wing size.
In simple terms: Eagles ride thermals they can’t control, limited by wing span.
Leverage natural forces but recognize limits.
