No matter how hard you try - whatever attempts you may make, the preparations made, the plans drawn. No matter how carefully it is planned, no matter the long hours of practice and study, the endless agonising - notwithstanding the silent meditation in anticipation of the moment - no matter of all these things.
It will only work if you believe. Wanting is not enough, wanting gets you by - you have to Need it - Need it like fish need water like fire needs oxygen, need it like earth needs water and the sky needs the sun.
When you need it enough - and only then - will someone else buy a round of drinks.
