It all kind of depends on what you kind of want out of it maybe. For some people like me that want to go into the film industry later in life may try to stay motivated by saying that "the more I keep on with this, the more I can improve and gain more experience for in the future so I can't stop now." Or if you are also like me and feel like you don't have as many subscribers as you feel like you should have and maybe don't have that many people watching your videos, then you could think to yourself, "Everyone has a hard time getting off the ground, it is the hardest part of any kind of business, association, etc. Eventually they get there though with the hard work. No one has ever gotten big off of stopping what they were doing and just giving up, it just doesn't happen like that." That's my piece of advice unless you have different goals or interests, then in that case...... I wouldn't quite know what to advise you to do because I don't know your personal goals or interests yet.
