"What's the point of living if it's useless?" -Others

If you don't feel useful, at least do good. It will make you useful.
Remember the words of someone I love. "Stay alive, even if you don't feel useful."

Do you guys know? There is at least one person who thinks that you guys are useful to him/her!

If you are discouraged, try to find happiness. If you can't find it, try looking again! There must be. There can't be none.
It could be that happiness comes from someone. ....Or something you care about!

But remember too. "Every soul, will surely taste death."
Surely all souls, whether it's us, humans. Or animals will surely feel death.
Wait for the death, don't you come to the death.
