i read THESE quotations many blue moons ago and they
still guide my actions today:
(1)
You are correct if you believe that you will succeed.
And, if you believe that you can not, you will still
be right.
(2)
You are within reach of your goal as long as you are
making a sincere effort and not quitting.
The moment you quit, you make sure that you will not
be reaching your destination.
