Fuck AI

what you refer to as comics books is one style. I assume you mean DC/marvel...

try not focusing on the end goal, but the steps to get there instead

I could start doing cyanide and happiness art within a week or two with no prior art skills.

one of the hardest things is just trying and putting in effort to get better at something you're interested in. giving up before you even try is the real failure. telling yourself it's not worth the effort is just denying yourself the payoff. set aside any amount of time you want at whatever interval you can manage (30 minutes a day, an hour a week, whatever) and you will only get better over time.

don't sell yourself short. if you want to do this, you can and the best time to start is now.

It takes years to get good at anything worth being good at. That's just life.

If you want to be good at something you'll find the time. Especially if you like doing that thing.

Getting to the level of a top-tier pro is hard, sure, but getting decent enough to derive satisfaction from the activity and make images people can enjoy isn't really all that hard if it's something you're actually interested in.

"Unless you have hours and hours to give for years, you'll never be able to draw anything like you see in comic books." And there it is.
