make friends:
finding a group to belong to, maybe a server for youtubers (im part of one myself) or just people to do collabs and videos with
find your style:
seems like the most obvious one but you seriously need to keep this one in mind, the more you do videos and the more people who watch you, over time you'll find a style that caters to how u like to play and what your viewer base enjoys
dont give up:
when starting out don't let low views etc discourage you the more you do this the more people will give you a chance and will come back for more
hope this helps and heres a video from a friend of mine who made a tutorial that might help:
