Don't expect gold after a day. It could take you weeks, months, even years to build up a fanbase, get a decent amount of subscribers, and start making a profit off your stuff. I know it sounds like something most people might know (and maybe it doesn't), but most threads from starting creators here (aside from the introductory "hi I'm new!" threads) are threads asking why their comic isn't popular, but their comic in question has only been up for like, a few hours or a few days.
If you've entered the comic business thinking you're going to be striking gold and making millions, you're in the wrong business. Making comics is amazing. It's rewarding, fun, and a great way to meet new people, make new friends, and learn new techniques when it comes to your own art. HOWEVER, it can be very discouraging and tough to make it through if you go into it expecting to be the most popular person after only two comics and a few hours of being up.
Don't be the person who hates being in this business simply because they set their goals too high right off the bat. Be the person who's in it for the love of comics first, and the business second. When it comes to this business, unless you have a tight portfolio under your belt and you aren't someone just breaking into it (which 99.9% of them are) if you manage to make enough money that you can live off them, consider that a bonus. Do it for the love of comics first and foremost, and then worry about the business later when you've actually started to build a fanbase.
Just do it /rides off into the sunset
