At my best (and this is not everyday), I'm able to see young artists flourish, older artists hone their amazing skills, and have my butt kicked by a great writer- and love it all. But that's my best day. When the emptiness in my head isn't a self-doubting, needy blackhole of indecision and self-doubt (did I say "self-doubt" twice? Oh well, it's not elegant, but it tracks).
But if I can push past that, get on a work schedule, and spend time doing the writing/art (and being grateful that I'm able to do that work), it gets better. And honestly, having opportunities to vent and make connections in a community of artists helps a lot too. It's nice to feel like I'm not alone.
I know that I'm never going to be the best version of the artists I most admire. I can only be the best me. And for every 100 comic panels I draw that I cringe at (always after the fact), there are a few that I'm genuinely excited that I drew.
I remember John Romita Jr. talking about his "deadline" style. He had to kick so many books out the door and sometimes his art suffered (with character inconsistencies/weird proportions/etc). But him sitting and doing the work has created a large body of work that is incredibly impressive.
One of the best things I did was print a copy of my comic (as a book) because it gives weight and tangibility to your work. It feels like it matters more. And when I see the panels on the page, yeah, some of them are deadline style, but they might sit next to a panel that I love and it feels pretty damn good overall.
To @Kelheor's point, when you can find the time and space to sit and hone your craft, it really pays dividends. I'm both blown away and inspired by the progress of so many people here. To see so many comics start off with good art but then find them cranking out masterpieces 40 episodes in, it's exciting. You can see it when people really apply themselves. I love seeing people becoming their best selves (and excited to see where it all goes).
I remember a moment in college when I didn't know what the heck I'd do (writing, film, comics, etc), dabbling with everything. I loved comics, but the second I saw a dedicated artist show off their amazing Daredevil page, I packed it up and leaned into film and animation hard. I felt I would never be that good and I dropped comics for 16 years (and that was such a mistake). I'm happy for where my non-linear journey brought me (it's damn amazing to work in an art field, I'm not complaining), but I kick myself for letting my love of making comics go. So yeah, I have a lot of catching up to do to be my best self, but I am grateful for the other skills that I acquired that I can put into my craft.
But all in all, thanks for expressing your doubts @aqua03. I feel that, even in doing that, it gives so many of us a chance to feel like we're not alone on our journey.
