Switching from 3rd to 1st person?

I believe it is better to be good at one of these two options and show that off as best as you can in your writing than to try and be adept at both. So i would continue writing in first person and try to master that.

Concerning your previous work there is only one question to ask. " Is it worth it?" or more specific
Do you believe your old work was good enough that you are willing to rewrite it or not? Because it will take quite a bit of time and unless you enjoyed those stories enough to spend more time on them i wouldn't do it.

 

From personal experience, first person tends to be easier to write when you're starting out. it's got the built in intimacy. Third person, requires a little more mental work and understanding to be able to write it in an intimate style.

Now to your actual question. Switching POVs like you're considering, if indeed you're 3rd person is as distanced as you think, is going to require a lot of work. You'll have to go through every line and make sure it fits in with a 1st person POV. In addition, if it's a multi-pov story, switching to 1st could be a problem.

If you have say 3 POV characters and all of them are told in 1st person, that tends to not be a good idea, because it tends to throw off readers in terms of remembering which POV charater's head they're in. I'm not saying don't do it in this specific case. I'm saying you'e going to have to overcome this issue if you have multiple POVs told from 1st person.

As mentioned above. The question is if you think it's worth your effort? How much of a difference do you think it will make to the final product? If it's not much, it's probably better to move on to the next story. That is unless you think it would benefit you in other ways as in using it as a exercise to improve your skills in some way.

 

You can get a first POV-like intimacy in third POV, it's called Close, or Deep Third, and I do it all the time. The problem with POV, is that the reason First feels easier is because it is easier...to do certain things, and unfortunately, those things are often the bad habits that make writing look sloppy. "I saw..." -type sentences are what make people cringe, and it's the basic translation of "He saw" in third, that made its own writer cringe when they felt it wasn't working.

Of course that's only one example, and the most obvious one available, but I really feel like the list is long. For that reason, I'd suggest you look up techniques of writing in deep third, and see whether any of it resonates with you. It might be the happy medium you're looking for.

Btw, I write in first, close third, and third, and what I find limiting about first, is that you can never gain the distance you can in third. For example, if I'm in a romance scene or a street brawl, yes, I want to be all up in my character's head: Less, "her hand slid up his back, tantalizing him," and more, "her hand...holy shit. It slid down his back and didn't stop at his waistband." Or, less, "he struck again, this time impaling the swordsman's shoulder. Right, left, he continued to throw feints and lunges." (and that'll go on for a page or two, just choreography) More, "He feinted and probed to test his adversary. Perhaps it was a bit indulgent, the amount of flourish he put into his movements, but he felt ready to prove something–maybe only to himself."

Yeah, those examples were quick, but the point is, that you can choose where to get more intimate with the character in third POV, like you can't in first. Plus, you can create some distance when it's appropriate (like when there's a mystery you aren't revealing, which I do a lot). I guess that's why I love third so much. But I do also love first. I just KNOW you can get the best of both worlds if you try some of the techniques. It's certainly worth a try, since rewriting several novels just to switch POV is a huge undertaking. At least give it a look and see whether it accomplishes what you feel you need.
