I find persistence over rated. For every girl that rewards guy's persistence when the girl play's hard to get there are ten girls who just want to use him and dispose of him as soon as they find someone who treats them as equal (a guy being strong, firm, who can stand up for himself, who doesn't take crap from anyone including women and who is not a door mat is what worthy women find attractive in a man). I don't buy into whimpering persistence and continuous asking out of a woman playing hard to get, asking out once or twice should be enough. If it's still a no then the girl can play those games with some one else.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
