It all comes down to how motivated you are. You have to constantly go out and find loyal subs. When you are small no one is going to find you because you will be flooded with bigger channels doing the same content. Unless you offer something special. It is important to go out and ask for tips, talk to others, and make friends. Do not do sub for sub. You do not get paid for the amount of subs you have. It is based off of views.
