If at first you don't succeed....

...give up in disgust. Punch the wall. Kick the door. Sulk. Scowl. Give yourself a hard time. Find someone to blame. Complain to all your friends. Curse your own bad luck. Tell yourself that you didn't want whatever it is that you didn't manage to get. Shrug your shoulders. Let a little time pass by. 

Focus on something else for a while and then... try, try and try again. (Most people only know the edited version of this old saying. Now you know all the story.)

Clouds come floating into my life, no longer to carry rain or usher storm, 

but to colour my sunset sky.  (Rabindranath Tagore)
