Don't stress it man. I've been on YouTube for 2 years under the same channel name, and I'm sitting at just under 400 subscribers. You should make videos you're proud of and that you wouldn't be afraid to show your friends and family. Get weird, be you, let your personality come out in your videos. If you try to put on a different face, it turns people away because they can tell. It took me a full year to learn that one, but once I started relaxing and being myself, I saw my numbers increase. Albeit not very much, but it does make a difference. You should always have fun with a hobby, and if it gets stressful you should re-think what you're doing while you're still a small channel. I do gaming videos and we all know that YouTube is WAY over-saturated with them, so I started making music as well. I've seen a pretty dramatic increase in traffic since doing that, and I'm having a blast with it!
