This is my main reason of why some people will never start on DTube, YouTube, anywhere really. In my opinion it all comes down to person's will and laziness. To be totally honest - most of us are lazy. That's why you should find what you love doing and only then, probably, film it and create your channel. Because, if you start doing something just to get famous, rich, etc, you'll most likely give up on it before it happens. Most big goals and achievements take a lot of time, so don't worry if you can't convince your friends or family members to do Dtube, it's certainly not for everyone. People that need to be here, will be. Just do your stuff :) And do it well :)
Have a good day!
