Sometimes a pause ,a step backward, a relook , a wait ,  a momentary stop or even a U turn may have amazing  wonderful unexpected positive results .
Wait patiently ,if required and you can afford.
A wait is always worth a wait and better than waste or haste .
Do your best but get not fed up of await.Sometimes a wait may be longer than expected ,but never mess or waste.
You cannot dictate everything every time or all the time .
Even Alexander the great did face the reality .Napoleon was not the exception  .
The Great Greek and those who ruled all the continents saw that time rules ultimately.
Those who did not quit have won and you know those winners.
That is good, you all must know them .
But there were fighters who fought tooth and nail , threw themselves heart and soul , left no stone unturned,burnt all the midnight oil,were perfect to a T but ultimately fell short of a victory ,success ,a win .
May be they failed to wait at some point !
I am afraid ,they could not wait a bit longer and grew restless a bit earlier. Perhaps a relook - they hesitated.
I do not know- they had a fair proposal of U turn and then proceed.
I can only guess .But I am sure ,you must not quit but be ready to change your course ,examine and reexamine your strategy and timing and a await,a pause sometimes  saves all the ruins and brings the brightest sunshines of your life and hope.Many a dreams came true only after a wait when none could really wait but the wait was forced and became boon for the Humanity ,Mankind and we all ..

MUST WAIT IF YOU CAN AND ANOTHER WAIT WHEN YOU CANNOT
