@GeneralR: As with many things, you learn by doing. You can ask how to make jokes or characters, but it's a bit like riding a bike. You can be told how to ride, you can read all the manuals, but in the end, you have to figure out how to balance up there yourself. And you will fall down. But you keep at it. Heck, here's a mind bending video showing how even a small change to something you think you've finally mastered can completely derail you: http://io9.gizmodo.com/could-you-ride-the-backwards-brain-bike-1700940131
Perhaps start by shifting your mindset. I know a lot about the "I'm bad at..." refrain, though where I am, often the refrain is "I'm bad at math". That particular statement actively irritates me. (I bring it up since you said you're more 'technical' minded. Also, I'm a math teacher.) No one starts "bad at math" any more than they start "bad at writing" or "bad at drawing" - it's about how much effort goes into mastery. How much we're willing (or able) to invest.
And yes, for one person, improving certain skills might take a day, whereas for another person it takes a week to reach the same level. That doesn't make the second person "bad" at it - there's different learning/writing styles, and for all we know, the person who takes longer is gaining a more nuanced understanding. In that respect, math is not so different from the arts (though I grant that I see math as art). As a "for instance", a friend of mine had to retake high school english courses more than once. Given that, and what teachers said, he figured writing wasn't his thing. Now he writes a weekly column for a website and has been in 10 NaNoWriMos. He didn't get there overnight.
@POV Thoughts: Yeah, not just harder to do, but harder to tame, IMO. It well be my Achilles heel. Even back in my fanfic days, I'd tend to write separate parts from the perspectives of separate people, and I'm still doing it in Epsilon. And it's an issue brought up about "Time & Tied" (though I'll argue it's better now than the first draft 15 years ago, when I usually slipped into omniscient). But I'm FAR too restless to stick with one character for more than a couple parts. It may yet be (have been?) my undoing.
