In Naruto, there weren't many things that could give you a leg-up without you being born with it or having crazy drive.
As a civilian, you unfortunately lacked any sort of kekkai genkai, or a clan to teach you exclusive jutsu.
Having shitty-chakra control as well ruled out being any sort of Tsunade.
And you were lazy enough that you didn't want to take the path of Maito Gai and become a taijutsu beast.
But there was something that caught your eye. Something, which if you could use properly, would give you an enormous advantage even without being born lucky.
Fuinjutsu.
An amateur computer programmer in your past life, you decided to test out the seal you'd come up with based on the couple of books you'd read. They hadn't been in-depth (damn library restrictions), but you thought that you'd gotten a decent hold of the basics.
Activating the scroll, you grinned as it began to glow…
…and promptly blasted your head off.
Epilogue:
"Did you really think fuinjutsu was easy?" Uzumaki Kushina said in the afterlife, with a sickly sweet smile on her face.
You're on your own, Uzumaki Mito looked at you, pityingly.
