Best Topic for blogging and Dtube???

I was considering this inquiry long back in light of the fact that I actually found no solution about it. In reality, I didn't have much learning about the digital money with the goal that I couldn't break down the market of it which is a much-consuming subject now a days.

Along these lines, I'm considering a subject of "Self-Improvement" into the discussion. I think with this topic I can help others to improve themselves internally and can also help others in adopting a better lifestyle.

Life is all about believing yourself and not giving up no matter what happens.

As I believe that one should only be satisfied when is able to say himself the following words:

So I wanted to ask you do you have any other ideas for me? And the other thing is that I also want to start putting videos on the Dtube but I don't know how to use the softwares. And my other tension is about coming in front of the camera.
So what should I do now? How should I make videos on the Dtube?
