The most important thing is not to give up.
Don’t ever give up on the world. Don’t ever give up on any human being. We are all created in God’s image, every one of us is so very holy. Every one of us has the capacity to be so good. We just need good friends to remind us.
The difference between young and old is: Those who still believe are young. Those who gave up are old. ~ R’ Shlomo Carlebach zt”l
