Selfish love is only considering your own feelings; Selfless love is to consider the problem from the perspective of others and think more about others.
Selfish love can't tolerate any grievances and unwillingness, and neither can sand; Selfless love is an unrequited effort.

Love is the key factor to ensure the continuity of mankind. However, when we love someone, we can only get (but not necessarily) the harvest of being "loved" after giving "love" selflessly, which is also the meaning of Laozi's famous saying "I'll take it from you first".
There are many different forms of love, but only true love is pure and beautiful.
Some people say that love is selfless love. Some people think that true love must be mutual. Some people think that true love must be rational love; Irrational and one-sided love for English is called "crushing".
The misuse of "love" devalues the value of love. But there is still true love. Since the theme of this article is "love", we must mention a passionate but true and pure love. This is the touching (though controversial) love between John Lennon and Yoko Ono Lennon in The Beatles.
