Do you guys think it’s okay to take breaks from a project you’ve been working on for awhile and/or that you’re fatigued with to work on another?

Well, if you're going to come back to it? Sure, but if it's just going in the pile, I don't think so

Also, generally, if your qustion is: "Is it okay to take breaks [additional information]?", Than the answer is yes

@SoldierOfCode I definitely want to go back to it, I’ve just been working on it a bit too long (without a lot of progress) and I just want to make some other stuff to boost my productivity and come back to the main project with a clean head.

You can ramp down your efforts without giving up it completely

absolutely, that's good practice.

Absolutely, at least you'll get to know if it's working for you

Yes, and you can also ask someone else to take a look if you've been stuck for a while, maybe they know a better way than what you're trying...

If you need a break don't take another project... You won't finish it anyways.
First rest... Play a little, watch some movies. Then if you dont feel like continuing on they project start a new one
