Hope what is Hope and What does hope do?

I was reading updates on Twitter to day. I came across greenhousedoll who had a link to John Maxwell's article on How to Be a Dealer in Hope. I like some of the things he spoke about on hope. For instance did you that Napoleon said: “Leaders are dealers in hope.”
Leaders deal hope. So what is hope? Why is hope so important to us? According to Maxwell's article 'Hope is a power that keeps us going in the toughest times of life.'
He has a list of what does hope do for humanity?
1.Hope shines brightest when the hour is darkest.
2.Hope motivates when discouragement comes.
3.Hope energizes when the body is tired.
4.Hope sweetens the bitterness bites.
5.Hope sings when all melodies are gone.
6.Hope believes when the evidence is eliminated.
7.Hope listens for answers when no one is talking.
8.Hope climbs over obstacles when no one is helping.
9.Hope endures hardship when no one is caring.
10.Hope shines confidently when no one is laughing.
11.Hope reaches for answers when no one is asking.
12.Hope presses toward victory when no one is encouraging.
13.Hope dares to give when no one is sharing.
He points out also, “Hope brings the victory when no one is winning.'
He makes a list of 'How do leaders offer hope to people?' I looked at that and asked how can I offer people hope? The same way. I would like to point out to you how you can get hope?
1.Change your way of thinking. My partner, Kevin, always says, 'stinking thinking leads to stinking living.' Live outside of the negativity.
2.Win some small victories in your life.
3.Know that I believe you can get through the worst of things.
I am hoping that this will make a world of difference in your life as it has in my life. I have stop as much of the negative thinking, work on small victories which have given me more life, and I now believe I can get out of every situation not to say it happens instantly.
Hope grab on to it.
