Let's look at her life's important decisions:
Situation 1: When Mallika mocks Jassi's taste after finding out that she chose her engagement ring (*way back, when the serial was actually absorbing*!)
PJS's Solution: Took an indefinite vacation (where she met Purab!) without leaving any contact number
Situation 2: After she reads Raj's insulting letter and later overhears him coercing Armaan to marry someone else, she misunderstands Armaan's feelings . (*before diclosing the identity of Kohinoor, when the serial was tolerable*)
PJS's Solution: Ran away to Mauritius in a bid to never see Armaan or the GM gang again.
Situation 3: Back in GM, when it's important that Jassi signs on some papers, and lawyers are banging on her family's door! (*while Jassi is slowly having a makeover, when the serial was barely tolerable*)
PJS's Solution: Remains in Mauritius. Allows her family to suffer in isolation while she is learning the tricks and trades of beauty. Again, doesn't let anyone contact her!
Situation 4: When Mallika leads a negative publicity campaign on Jassi and her family, and Billu Walia throws her belongings out in anger! (*Jassi finally comes back to Mumbai only to find her family pissed off, when the serial was slowly going on a downslide!*)
PJS's Solution: Runs back to Purab without having the guts to face her family and the situation., and becomes an supermodel! Later, hides herself behind her new face and extracts revenge from Mallika and Raj!
Situation 5: When Armaans' parents decline to hold the engagement in Amritsar, and instead want a lavish party at a 5-star hotel (*when the serial lost its track and was quite unwatchable!*)
PJS's Solution: Jassi packs her bags and runs to Amritsar....while her poor fiancee holds her pallu and follows her!
Situation 6: Armaan's accusation that Jassi slept with CJ! (*when the serial has become totally unwatchable!*)
PJS's Solution: Jassi runs away to Nainital and becomes a widow (kya logic yaar!)
If it can work for her, why can't it work for you?
