This is a fairly personal issue with me. I don't know if this will help you, but it helped me.

When I first started my degree in computer science, I had to tank 3 years of a history degree. Those 3 years were basically a waste of time. I knew people who got married before I even really knew what I wanted to do with my life. I was fat, working a dead end barista job, living with my parents, and playing WoW and that was it. That was what I got from 3 years of history. Part of it was depression, but the bigger part of it was that I didn't learn the real shit yet. I was waiting for someone to stumble across my clearly hidden genius and make me an overnight success.

That doesn't happen. The opposite happens. They stumble on what you're doing and they try to tear it down, with good intentions and bad. Sometimes they're absolutely right, but I wouldn't have known the difference, because every time something I was doing was called in to question I backed down. I let them break it, no matter what it was. Idea for a book, for a program, for a game? Been done before. That's how other people see it until it's out of your head to some degree, because they can't imagine what you're doing different because they aren't you. So you have to fight for it, even if you eventually realize that they were right. Hey, if you're going to say that you have a million dollar idea and it's a locations app for beer pong cups? That's a bad idea. But fight for it.

Nobody else is going to be able to fight for your new ideas, period. They can't. The ideas aren't even born yet, they can't see what they'll look like. You know why say, PewDiePie is big? He pushes the shit out of himself. I don't think the guy is particularly funny, I think his act is a little grating, but he works his ass off and pushes what he's doing. By all reports he genuinely enjoys what he does.

If you want to rise above the millions of other let's play channels, the other writers out there, then you have to push for it. Otherwise yeah, you'll get lost in the noise, same as everyone else. If you fight for yourself though, if you take what you're doing and improve it and run all the way with it? You'll get somewhere.

I mean shit, DarkSidePhil has a semi popular channel. That's your competition. Somehow I think you'll find a way.
