You can go 3 weeks without food.
You can go 3 days without water.
You can go 3 minutes without air, but you cant go a second without hope. (Anonymous)
Think of hope as being like a flame. Sometimes it burns brighter than at other times. Sometimes it might flicker and look a bit shaky, but even when it’s shaky, it can always be re-kindled and brought back to life. Just as long as it never goes out, it doesn’t matter how shaky it gets, just keep the flame alive.
