Reusing homemade chalk paint

I've read dozens and dozens of all things re: chalk paint. And they all say "can't reuse, don't reuse, yada yada yada". Yet...I ALWAYS reuse mine;-)

Call me cheap or whatever, but I always mix too much and have leftovers. I couldn't possibly let it go to waste! Storing it in glass w/ a lid will keep it best, but I've also used cheap sour cream containers etc. If it's even remotely still pliable or paint-able in this case lol, I'll use it!!! If it's thickened quite a bit, I just add water. I like my c.p a little on the thinner side anyway, so I almost always add water to get the consistency I like most. Been at it for 6+ years and haven't had a problem reusing it yet! Hope this helps;-)
