Happy New Year 2014

For a happy New Year, just stick to some simple and basic rules. Have faith in yourself and your abilities. Count your blessings before you cry on your misfortunes. Learn to take each day one at a time. Create opportunities for yourself for quitting is never an option. Above all accomplish all you take under your wings – never abandon without completion.
