What would be your reply to, 'What do I do to get me passionate while thinking and doing; and finding my real self?'...Manish Kumar Agarwal

You are right, nothing would succeed with disinterest, having passion of what you think & do gives you satisfaction & renewed energy, simply saying reverse the formula, better think & do what interests you, think & do what inspires you, do it with passion, passion grows your inner self, inner beauty, perfection, satisfaction and the reason to live.
