The biblical principle of hope can be applied to everyday life in many different ways. When writing about this topic it is a good idea to examine the concept of hope as it appears in the Bible first. Look for examples where people or individuals had to have hope, or a vision, to carry them forward - and that is often aligned with faith. Then, look for similarities with our everyday lives today.
For example, the Israelites kept on hoping and praying for deliverance and that they would be led into the 'Promised Land.' Moving on to the New Testament, Jesus often offered his followers hope, sometimes in the form of miracles and also by telling them uplifting stories or parables where people had had faith and overcome obstacles. He said to the sick woman 'your faith has made you whole' because she had dared to go beyond reason and have the hope and faith that he would help her even though she dared not ask directly.
Today we have all the same challenges, and also some modern ones. Despair is the opposite of hope and some religions believe that to give in to this is cowardly and shows a lack of faith in God which is a crime against the Holy Spirit. There is much conflict and bloodshed in the world but if goodhearted people don't have hope and a vision of peace, then the world could give up on the prize. An example of hope therefroe might be to join a peacekeeping charity, Israel/Palestine perhaps or Pakistan where professionals are working to bring young people together through education charities.
