What is a decent amount of trophies now?

I dropped off this game year ago and thought I'd give it a download again and see what's new. I've been playing for about a month now and I'm gaining trophies like I never did before. So what is a good amount of trophies to have now? Like when does it get REALLY sweaty, as that's when I just might cave and stop again as I only play it casually when I have a break or something.
