Yes, I'm confident in my channel.
I wasn't originally, because I never set out to have a channel, it just sort of happened, after I put up a few videos embedded in my web pages.
It's a learning curve, and confidence grows as you try things and hopefully succeed.
YT has boosted my confidence more than anything else I've ever done.
These days I'm happy with the way the channel is going, the viewing community seems to have accepted me, is strong and good, and the channel makes a few dollars.
Don't be afraid to try different things. If it doesn't work then cross that idea off the list.
As they say - No guts, no glory.
Cheers Rob
