My two cents...

If you're a beginner still, and it seems you are, I think it's way too early to make any kind of pronouncements on what you can and can't do. I know this from experience -- I have a weak wrist and posted a similar thing awhile back about how I absolutely, positively would not be able to physically manage barre chords.

Literally a week later, after playing around with them a bit, I figured out how to make it work. Now they're just chords like all the rest, albeit a bit more challenging.

Someone else already said time and practice will solve most of it. Not to say that you may not have some kind of physical limitation, but again, it is WAY too early to be able to tell that with any kind of certainty.

So play on... you will be surprised at what time, practice and growing confidence will accomplish.
