/***********************************************************
When you are inspired by passion
and you want to live for the current moment
When your every thought and action
has the power to become the story of your future
When difficulties stand to demolish your Glory
Just remember that Life is a 'Golden adverse Story'
Withstand it to acheive your passion and dreams
more amazingly more easily.
Why then? When writing the story of your Life
You want to Let someone else hold your pen
