No he didn't. Technically, we don't actually know how Gohan became a Super Saiyan, because we only see brief scenes of Goku and Gohan's training in the Time Chamber after they cut away from the main battle. We pretty much get a scene of Goku telling Gohan to "get mad" ("Imagine that Freeza's trying to kill me" bullshit), then a scene later of Gohan turning a SSJ and barely managing to maintain it for more than 10 seconds. I guess, with three other Super Saiyans, Toriyama didn't feel the need to actually explain how the fourth one (and probably the most important character in the Cell Arc) got it, and it wouldn't really matter anyway, because it's ~GOHAN~ (yeah, I know people usually use that for Goku, but that's probably the simplest way of putting it).
I think that his reason simply was so uncomplicated that it didn't have to be explained.
Right when Goku and Gohan entered the ROSAT, Gohan asks Goku : "Do you think that I can become a SSJ?" and Goku answers "Your future self became one, so you should be able to do that aswell". Those are not exact quotes, mind you.
During three years, Gohan trained with Goku and Piccolo, watching their huge strength, and during those three years, he lived under the pressure of getting stronger, so that everyone wouldn't die. With Goku, Vegeta (whom they couldn't depend on) and Piccolo, he was the only one strong enough to be able keep up.
After seeing how useless he was against the Androids, I think that he had built up enough despair. Three years for nothing.
So, when Goku told him to imagine pretty much "everything that could go wrong", Gohan managed to put that feeling into it, causing rage big enough to make him achieve SSJ.
It's not because of that he is ~GOHAN~, Vegeta's way wasn't either something awesome...he simply got mad at himself for having limitations, like a little bitch. Wow, that's more awkward than Gohan's way of transformation.
It's just that people don't take into account that Gohan is:
1) Around 20 years younger than his fellow fighters
2) Was thrown into the fighting ring at the age of 4
3) Never really made any great difference, even though he worked hard
4) His damn brain until Buu saga isn't developed enough to be able to process the hell he has been through, thus rage is the only thing he feels in dire situations. This influences on his powerlevel. It's some kind of psychological defense mechanism.
5) He did 100 times better than anyone in his age ever, except for Goten and Trunks.
He did actually work hard for his power. Let's go through this shall we:
He was born with a high powerlevel. This is explained as having to do with him being a hybrid. But when he was abducted by Piccolo, he actually didn't know how to access that power. And he learned to do so when he was all alone in the desert for 6 months, fighting for his life against wild animals.
He learned to fight against Piccolo, and improved greatly enough to be a force to be reckoned with against Vegeta and Nappa.
Fast forward a bit. Gohan leaves for Namek. After getting his dormant powers released, he can access more of his power. This power isn't something magically created, it's the power he has worked hard on achieving.
He gets, like, two zenkai during the Namek arc (one after he fought Recoome, another after he was healed by Dende against Freeza). Vegeta gets three (one after his Zarbon fight, one after fighting Recoome, and the last one after Kuririn's blast), Goku gets numerous ones.
And you say that he is sitting on his ass all the time and getting his power on a silver plate?
He trains for three years against Goku and Piccolo, and is still useless. He becomes a SSJ,
after Goku and Vegeta, by
the same method: RAGE.
Then they find out this little guy has
even more power than the rest: His training prior to the Androids arrival and in the ROSAT has paid off. It's simply because of his hard work.
So, with his unstable psyche, he becomes a SSJ2.
7 years later, Gohan's power has decreased. But he still has lots of latent power, which is mentioned again a couple of times by Goku. He gets that released, and becomes powerful.
And he didn't obtain that power by snapping his fingers. It all goes back to all the hard work he has put into his training, even though he almost never had any good results from it.
Also, his training with the Z-sword increased his power to even higher than Goku's in base. So, if he could use SSJ3, he would outclass Goku in power.
So when all the boundaries were released, all his power that he has worked hard for were released.
Of all the Saiya-jins, he always were the only one not trying to cheat himself into having more power with using transformations.
If you don't notice this, you simply just hate the character, and have missed the points in Gohan's story.
