Sometimes it's hard not to feel just a little bit envious, but I never let it go too far. I mean, take the Black Nerd for instance. He's basically a 'professional TMNT fan'. Dude, I'm a huge TMNT fan, I can do that. Someone invite me to exclusive cons and behind-the-scene TMNT events and cameos with the Critic and Nerd too. LOL. But what can ya do right? I guess it's not 100% bad to be a little envious at times, just don't let it consume you. Use it to get even better at making your videos.
On a more personal note, one of my friends that appeared on my show several times eventually made his own channel and once he started doing Phoenix Wright voice overs, his channel exploded. He actually buys his own $100+ equipment based off the earnings from his channel and hosts panels at cons giving advice on voice acting and channels. Am I envious of him though? Oddly enough, not really. He's still a great friend, the 'power' never went to his head, and he never rubbed it in my face or started acting all smug. He's basically the same great guy before any of the Youtube stuff started so no, I could never envy him.
