Rashi says that Yaakov was entitled to the bechorah because, if you put two balls in a narrow tube, the one going in first will come out last. One could wonder whether this is accurate since babies move around in the womb. Moreover, Rashi already commented that there had been attempts by Yaakov to leave (when Rivka passed a Yeshiva). It would seem from Rashi that while Yaakov attempted to get in the front position, his efforts were always prevented by Eisav. Yet, Yaakov never gave up. His name Yaakov defines that struggle and that he never gave up.
The kochos, which the Avos obtained by withstanding their own nisyanos, are imbued within us. So the next time you are faced with a struggle and you don't succeed, don't give up because you are Bnei Yaakov and Bnei Yaakov don't give up.
Thank you, Hashem, for helping me through all of my struggles and for helping me get up even if I slip or fall.
