[SPIDERMAN] what is Green goblin goals and motivations?

I'll admit I don't really read much comics, 90% of what I know of Spiderman are from cartoons I watched as a kid and the movies, but in all of those I don't really remember GG having any goals apart from being a dick to Spiderman just because, and maybe "getting rid" of Nosborn problems by violence, but apart from that why does he do what he do?

Varies depending on the medium. Most of the cartoons and movies center around Norman’s mental instability and desire for power going over the edge when exposed to the Goblin formula, turning him into a supervillain to achieve those goals. And when Spider-Man starts stopping him, Green Goblin grows to hate the wallcrawler and want to crush him under his heel. 

In the comics…honestly, he kinda just outgrew that phase by now. Norman flat out admitted to Peter that their conflict was the only thing that ever really made him feel *alive*. Not being a father or husband, not a successful businessman and scientist, not having the respect of everyone, or even being a supervillain ready to take control of the criminal underworld, but having a genuine opponent who hated him as he hated them, but neither could fully defeat or break the other into gaining victory. 

Even in Dark Reign, when Osborn objectively won against the superhero community, what’s at the end of his wish list and the only thing he truly has passion for throughout the time? Killing Spider-Man. What does Norman do when he loses all that? Shrug and go back to fucking with Peter. The man doesn’t care about power or anything outside of how it can be put to utterly crushing Spidey into the dust. 

TL;DR: Green Goblin’s character development is becoming Spider-Man’s Black Manta.
