It's a funny thing - when I'm crazed with work spending time with my children relaxes me. Yet at the end of a long weekend with them the very thing I need to relax is a little work and time away from them!
It's just an unhealthy way to approach something trying to outdo your last thing. You've gotta trust evolution you've gotta trust that the bar is moving that you don't need to force the bar. It'll just happen.
