Hello @andretarina,
Welcome to DTube and Good Luck for your journey.
Remember the Golden Rule,
Be consistent, bring quality content and try to add value to @dtube.
You can follow some people like @nathanmars, @clixmoney, @captainbob, @bobaphet and many more. You observe what they do and what is their style.
I would suggest you to join some communities where you will be under constant touch with reputed people who can help you out with your troubles.
And try to upload atleast 1 and max 2 videos a day.
I am always there, you can knock me whenever you are in need.
