/***********************************************************
	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
