Let your smile change the world, but don't let the world change your smile.
Being happy is a state of mind, and even those who struggle in their daily lives can find things to be happy about if they only look hard enough. Part of being happy is being content with what you have, instead of striving to have more than others or wishing for incredible wealth or fame. Happiness in life can be caused when you are satisfied with your achievements, or when you help those less fortunate. Romantic relationships and close friendships are also reasons for being happy.
Let your smile change the world, but don't let the world change your smile.
Love is not about how much you say 'I love you', but how much you can prove that it's true love.
Be With Someone Who Brings Out the Best in You, Not the Stress in You.
If you can make somebody, anybody happy do it. The world needs more of that.
