Don't do it for the money. It probably won't work out.
Be prepared for mean comments. Don't get emotional about them. A lot of them are trolls or have issues in their lives. Just ignore them and move on.
Don't expect much of anything; views, comments, likes/dislikes, subscribers, etc.. for a long time.
Have fun.

Write scripts.
Make all videos on the same theme.
