Everyone will experience or have experienced cloudy days. Soon after the clouds go away and the sun shines through.
In some countries, particularly those up North, cloudy days may last longer that we would like them to.
In our lives, there will be cloudy days and for some it may seem that the sun will never shine through.
If you were to take a flight above the clouds, you will see that the sun shines all the time. Have faith and stay positive, your cloudy days will pass and your sun will shine brighter that you expect.
