Is it a good idea to have my own youtube channel ?
What brings about that desire?
I feel like I'm an interesting person with my own point of view
Don't keep it a secret any longer. Start your own channel and pursue the things that bring you joy.
What if no one cares?
You shouldn't worry if people will like your channel or not. You do things for your joy not for others so go ahead and create a channel. I'm sure you'll get a positive response.
