"We only have to worry for tomorrow. Then, how come  'Tomorrow' will worry about 'Tomorrow'?" 

Let us 'Dream' about tomorrow! 

Let us 'Plan' about tomorrow! 

But, let us not WORRY about tomorrow! 

Worrying about tomorrow is nothing but worrying  today. 

Worrying today is nothing but spoiling today. 

Spoiling today is nothing but losing today. 

How come we gain tomorrow if 
we lose today? 

today is the day! 

Today is the Day, to start, Tomorrow's SUCCESSFUL  LIFE! 

If we win today, then, we can win tomorrow also! 

If we live today, then, 
we can live tomorrow! 

So, let us live today! 

Let us live our life today!
