"Deep down you know you can be remarkable. You shouldn''t settle for anything less than your best self, reaching ever closer to your potential--whether as a leader or in any other part of your life."
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.
