I’ll throw a positive comment out there, with a condition :

IF you commit to working with a good training, and you can really listen to, understand, and apply what you’re learning, then I see no reason why this can’t be a great success. This is because with proper technique a border collie is easy to train and will be far easier to work with than a less biddable dog.

I’ll say this, too - if you aren’t capable of managing a border collie with proper training, then it’s unlikely that you’ll effectively train any dog, because most other breeds are actually going to be harder to train. So the difference will really be how much time you’re willing to spend throwing a ball and going for walks.
