Hi! After a while, you get more secure in your videos, and usually, you won't receive regular negative comments until you have over 1K subs. Your friends and family should totally support you with your channel!!
one of the hardest things is consistency with posting due to motivation since your motivation levels can change depending on the week. also since consistency with posting is so important, missing posting dates is not going to help your channel grow.
i am thinking of doing a podcast on my channel too and i would probably make a separate channel just for the podcast and one channel for vlogs and other videos. this will help viewers watch what they want to see.
