How do you create a "well rounded" character that isn't likely to bore or throw off your readers? I've been trying to stray away from making characters that you've described and to make sure my characters aren't just completely flat but it's hard... any advice?

well, giving them a good motivation… that’s pretty important! characters that have a long-term goal that you can make stories around!

GK had neverending goals of finding more treasure and artifacts! which led him on many adventures and quests - and, well, it’s also what determines others’ worth to him! so having something that helps put your characters’ existence into a sort of.. um, i guess, something that defines it? that helps a lot in letting you think about why they’d act a certain way, and then you can get to the intricacies and the little details and side thoughts once you have an overall goal figured out
