     What kind of life do you seek for? One that is frustrating and full of complaints every day? Or one that

is filled with thankfulness, gratefulness and a positive mind?

     The moment we open our eyes each day, we should be grateful that we are still alive. We are given a

brand-new day. We are given another day to love. We are given another day of hope. We are given another

chance to do whatever we have failed to accomplish. Those who have chosen to leave this place do not have

any second chance.

     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.

     By being thankful and grateful for our personal health, we will focus our attention on it and we would

want to have a better well-being for our health. We will want to eat healthier food to nourish our body. After

all, the body is the temple of our soul. We have to treat it well so that it can carry us a longer journey in life.

     When we face problems in life, be thankful and grateful too. They are designed specificall 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.

     The year 2010 has come to an end. Have you achieved what you aimed for in the past year? Be grateful

for those you have achieved and especially for those you have not-both successes and failures. Failures and

mistakes will give you valuable lessons. So, pick yourself up and try again this year. Good luck!
