Sometimes we think about the pointlessness of things we do... and we know we cannot help everyone... I like to share a zen story that probably changed my way of thinking. I hope you'll enjoy as I did:

Zen master Ryokan was walking on the beach. A storm had just blown over. Hundreds of starfish had been washed up by the waves; they were beginning to die in the sharp sunlight. Ryokan picked up the starfish one by one and threw them back into the sea. A fisherman who had been observing Ryokan came up to him. "Why do you do this? Every time there's a storm, this happens. You can't save them all, so what difference does your attempt make?"
"It will make a difference – to this one," replied Ryokan, as he flung yet another starfish into the water.
Make a difference to someone today. Even if you help one person, you have made a difference.
