That time thing, where does it go?
Well, here's what I do:
Keep it nice and fresh
And by that I mean, I don't sit to long with one thing. I make a thumbnail story board when coming up with the pages - in general I make 12-ish pages at one go (but it depends on the story, it could be more, could be less). For this I often sit somewhere with no Internet around, like a café but it's different for everyone. Making a marathon comic like a 24 hour comic is perfect for coming up with stories and then I don't think much about the panels being all perfect, I just tell the story.
When I've gotten that out of the way, I draw up the pages (and decide if the storyboard thumbnails are good or if anything needs to be changed. Drawn bigger, from a different angle or removed), make the panels on all the pages (this is no matter if I draw by hand or digital). This is to tell myself that I have these pages, these panels to fill out.
If I draw by hand, I draw the panels with a blue pen. No inking! Just drawing. If I work digitally I might just photograph the thumbnails and import them to Clip Studio Paint. That saves a lot of time
When inking, I try to do it fast. By hand I'm limited by the wet ink, but the most important thing is: I do the fun and easy stuff first and just a little bit on the hard stuff. I work maybe 30 minutes/page and then switch to a new page, just to keep it fresh and clean That way I can keep up the pace, because after a while you get tired of the page and slow down.
When all of the pages are inked, I switch to coloring and work basically the same way. 30 minutes or so/page until I'm finished.
Sometimes I keep little paper notes around my desktop screen where I've written down one page number/note. When I've finished a page I get to remove that little note and tear it, crunch it, just throw away or whatever I feel like. It's very liberating!
Good luck!
