We should be grateful every day.By being grateful, we will treasure the things around us.We will learn to appreciate life in a better way.Treat others better and find ourselves in a better mood every day.When we are thankful and grateful for the things we have, the universe tends to give us more.

When we face problems in life, be thankful and grateful too.They are designed specifically for us so that we will be stronger and wiser.We are like a strong oak tree, facing the harsh weathers time to time.After each storm, we will grow stronger and strengthen our foundations for the next harsh weather.
