Thank you so much for advice and encouragements, sir. In general , my risk acceptance levels are high. What still holds me back at the moment are these facts

1. I will be entering into young people dominance world. Most vloggers what I have seen are at age of 18-30, while myself being more then twice of that. Am I not to old to learn all these modern things? :)
2. I understand the only language it can be successful, would be English. Which is NOT my native language. And I have not ever lived in English speaking country. Typing is more simple, I can use big G, other translation apps. Spelling checker is with me all the time. In video, the voice goes right away, and no really much chances for editing, post-processing , etc. This is scary, believe me. Doing it in Lithuanian - would be doomed from day one, no doubt.
3. I never got any practical advice from any existing successful vlogger. Regarding techniques, tricks, hardware, software, etc etc. Chances are my own imagination how to do all this - is not quite right .
   But...seeing so many advantages in video mode, the temptation is really big. Maybe one of this summer days. Maybe soon...
