The art of living does not consist
in preserving and clinging
to a particular mood of happiness,
but in allowing happiness
to change its form without
being disappointed by the change;
for happiness, like a child,
must be allowed to grow up.
Before you start some work, always ask yourself three questions -
Why am I doing it,
What the results might be and
Will I be successful.
Only when you think deeply and find satisfactory answers to these questions, go ahead
I am only one,
But still I am one.
I cannot do everything,
But still I can do something;
And because I cannot do everything
I will not refuse to do the something that I can do.
