How to start an information security blog and YouTube channel. and How can I add a new approach?



Hi everyone, I am a hacktivist. I would like to start a information security blog. But there is lot of bloggers and highly paid blogs. I want to start with writing a Technical publication as magazines and books. I have strong experience on teaching the online classes on an Information security. And further I will add the security services too. If I start with this platform then have a future scope on this platform? I want to build a good and friendly website for this one. If anyone give me the suggestions and guide me how to start or where I can start?

Thanks in advance
