PewdiePie was a more laid back in his earliest videos also. Hmm...what could have changed that caused them to be a bit more upbeat? Oh, I know. Millions of dollars! lol. I know if I had tons of money rolling in I'd be pretty damned upbeat too. I'm only half joking about this, though. Success breeds excitement and a genuinely upbeat attitude while stagnancy breeds indifference and doubt. It's important to have realistic expectations with regard to time frames and success so you do not get down on yourself unfairly. It's equally important to work hard at coming up with great ideas for videos. You can have the most electric and upbeat personality in the world, but if you're showing how to craft something simple in minecraft (for example), you're not going to get people interested. The first person to upload a Sims video where they drown their Sims would have gotten a lot of views on that video regardless of their tone of voice, attitude, excitement, etc because their content was compelling. Content>Personality when it comes to views. Have both and you're in great shape. Equally important, on the other hand, is the ability to evaluate your channel after you've given it a fair amount of time to decide if it's an idea worth abandoning in favor of a new direction or even a new channel.
Good luck with your channel!
