I have learnt that....

By changing our thinking,
We change our beliefs;

When we change our beliefs,
We change our expectations;

When we change our expectations,
We change our attitude;

When we change our attitude,
We change our behavior;

When we change our behavior,
We change our performance;

When we change our performance,
We change our life;

Life is like a book of three pages -- first page is 'birth', last  page is 'death',
center page is 'empty', it is up to us how we fill our page.
