All I can say, giving you advice I really ought to follow myself, is when first starting off, just do whatever amount of work you can do on it every day. You might feel done in a day, or in 7 days, or in 30, but it WILL get done with continuous work. In terms of coming up with stuff you like, you know what you like, my dude. Just do it. What you NEED to do will follow. Above all, know yourself. Don’t push yourself to do something you know you won’t be able to do, such as meeting a daily deadline (like I started off with with my Otayuri comic) or forcing something you’re not comfortable with onto your workload. The worst thing that can happen with any art piece is that you get tried of it or upset by it. Don’t let it go that far.
You’re just starting off, so don’t worry about it so much~ Draw, my friend. Whatever pattern works for you will come with time 😊
