In Emerald, I only trained my starter, Treeko. By the third gym, Wattson, he was level 39 (a Sceptile by that point) and the rest of the team were level 5 max. My cousin taunted me on how bad a trainer I was, so I released my Sceptile and raised a numel in his place. It took me months to recuperate from that bad decision to only train Treeko.

I also used my Master Ball... ON A FREAKING BIDOOF.

This........
Well, the only thing I can think of is thinking that you were allowed to leave the Elite 4 chambers and go to the Pokemon Center any time you felt like it.

It never occurred to me in Diamond that you could actually catch Dialga, Giratina or the pixies. I just assumed they were boss fights.

I forgot granbull was a fairy type.

Easy mistake to make.

The first pokemon game I was ever able to play was Sapphire, because I didn't have a handheld before that. But, ever since then, I'd teach my entire party HM moves, then I discovered they couldn't be deleted. I even taught HMs to Kyogre and Lugia.

It's only when I started playing X that my friend told me it's better if I just get another pokemon and teach it most of the hm moves that aren't powerful. So I taught surf to my Froakie and the rest I taught to a random bidoof. Which I got through GTS by trading my rotom for it

My friend was surprised that I did that, and he even got on me for trading my Moltres for Yveltal. I'm not a legendary collector like him, I won't use moltres so why not use him to get a pokemon I will use, like awesome Yveltal
Besides, I have two sets of the Kanto birds in Diamond and Platinum anyways. Unlike him, I don't plan on trading away my Xerneas for Yveltal, then trading all my pokemon to another friend to keep while I restart just to get Xerneas back in order to have both.

I spent my childhood believing that electric attacks would not affect rock-types because my Pikachu in Yellow couldn't defeat Brock.

It was only many years later when someone from pkmn.net told me that I realised.

I was breeding Houndours for the moves Thunder Fang and Sucker Punch, and I forgot that the Pokémon in the egg will always turn out to be the mother's species.

 In FR/LG, I used my masterball on an Articuno.

To be fair, I used my masterball on Xerneas, but that was because I couldn't be bothered with the hassle of fighting it any more and I'm sure it burnt itself.
