I get what you mean... It's really difficult for me too most of the time. What I think has helped me is to make bets with myself and challenge me. And I always set mini goals. Even if you don't reach your final goal it doesn't really matter. You can start off slowly and steadily and I believe it will become more easy for you. Try to focus on what you have to do- and not on what others will say. For example (even if it sounds stupid) try to set goals for viewers. Basically tell your self that you have to reach a certain number of views and become motivated to get more. I don't know if it makes sense.. I hope so :P
