The best way to not feel hopeless is to get up and do something. Don’t wait for good things to happen to you. If you go out and make some good things happen, you will fill the world with hope, you will fill yourself with hope.
Hope is important because it can make the present moment less difficult to bear. If we believe that tomorrow will be better, we can bear a hardship today.
As an actor, you hope to find roles that are challenging to you as an artist. Then if you are truly blessed, you will find that it also carries a message that you can impart to your audience.
