Over weekend, I was in Dallas and was sitting with a friend - talking depressingly about few events from life. Though, this may not be true but I liked it when he imitated these dialogues of Shahrukh Khan from movie 'Om Shanti Om'. I kept smiling all my way back.
"Ladies and Gentleman. Kehtey hain, agar kisi cheez ko dil se chaho to poori kaainaat use tum se milane ki koshish main lag jaati hai........aaj is baat ka bhi yaqeen ho gaya ke hamari filmoN ki tarah, hamari zindagi main bhi 'End' tuk, sab kuch theek hi ho jaata hai - Happys Ending - aur agar theek na ho to woh 'The End' nahi. Picture abhi baqi hai mere dost. Picture abhi baqi hai ...."
Try to say this line in your bad patch - "Picture abhi baqi hai mere dost" - it may help.
You can see both versions, (funny) and (serious) at youtube.
