Don't Give Up
There are two ways to express the number 4 in Japanese. The alternative way "Shi," ( 死 ) also means death. Which is why it is also considered an unlucky number in some superstitions. L4L was formed to defy negative self-thoughts, to encourage everyone to Live 4 Love. Not only the love for oneself and others, but also the love of chasing hopes, dreams, and whatever makes anyone passionate about life.
So, don't give up, stay strong, find that love, share it, until you see the end.
