用一段英文阐述奉献的重要因素：selflessness

Selflessness is an important factor in giving. Being selfless means putting the needs of others before your own, and being willing to give generously without expecting anything in return. When we are selfless, we focus on how our actions will benefit those around us, rather than what we can gain from giving. Selflessness is a key component of any act of giving or service; it encourages us to think beyond ourselves and consider the impact our actions have on others.
