Some of us are not from countries where laboral exploitation is romantized, where people won't take a vacation for "not wanting to be unloyal to the company or co-workers". Don't admire that lightly the fact that many mangaka overwork themselves, many isolate themselves, barely see their families, barely do anything regarding their health and don't have healthy lifestyles that would probably kill them young or in the job.
Many Oda fans are worried about his health and habits, we love One Piece but damn we wished he took more rest.
There was even the horrible case of Juniljus the artist of Roxana, that not only dealt with stress, anxiety and the pressure from following unrealistic deadlines from her Editor, she not only risked her health at the point of barely sleeping, but she also had a miscarriage that could have taken her life too.
If you want to sleep 4 hours a day, eating at whatever time, barely exercising or socializing, not being able to take breaks not even for health risk matters, then so do you. I know from personal experience is not worth it and you can definetly make a comfortable living out of art without being popular or having a contract with an editorial.
What do you even consider "putting yourself out there", what exactly do you want to achieve with your comic? Being rich? Being popular? Becoming a celebrity?
If you want to make a living out of this you'll need appealing art, appealing stories, knowing how to self promote, being constant, creating engaging content, being charismatic, being on time, know your current tools and resources, invest and learn new things, taking risks, taking pauses, and the most important thing figure out what is that thing that could differentiate you from the rest, then know how to exploit said thing. Besides figuring out any other reason why you're not achieving certain steps of your goal.
Everything is easier said than done, don't underestimate all the cons of hard work, you'll need to work smart too, taking shortcuts and taking advantage of certain resources. Trying your hardest doesn't mean draining your own energy, achieving a top goal or destroying your health in the process of reaching that goal.
