You need to know there is a light at the end of the tunnel.
First time in Anchorage, Alaska last week. On the way to the airport from the cruise port, there is apparently only ONE ROAD to get you there, it's a one way street with a tunnel over 2+ miles long. As I found myself on this long and dark journey, I peaked down the middle of the rows of people on the bus to see the light at the end of the tunnel. Huh - that's funny - a common saying that took on new meaning. "The light at the end of the tunnel."
I could see the light at the end of the tunnel, and although it was dark and seemed like it took forever to get to the end, with continual movement forward we finally reached our destination. On the other side of this long dark tunnel was nature in all its beauty. Wildlife, Mountains, Water, Snow - yet we had to go through the dark tunnel to get there - there was no other route.
Are you in the dark tunnel yourself? (hypothetically speaking of course.) You need to know there is light at the end. Keep your eye there and you will reach it.
There is always a light at the end - always. Be encouraged. Continue on. Take Action. Move forward.
