The heat is on all across the U.S. as we gear up for the 4th of July. And in Europe, the heat over the euro zone financial crisis seems to have abated for a day at least, judging by Friday’s big stock market reaction.

So is the euro zone financial crisis over? No, and a lot more work needs to be done. It’s also likely that Friday’s rally will give way to more selling pressure by next week. It’s the Madness of Wall Street and it’s simply how things go.

But here’s the thing: this week’s ability of European leaders to move toward getting something done–even if it is just a bigger band-aid–is one more indication that at the end of the day this crisis will be solved in someway. Oh sure, some nations will get hurt–and more importantly a lot of ordinary people that had nothing to do with the financial crisis will get hurt the most. However, maybe it’s time for everyone–especially those in the media, at hedge funds, bloggers and on Twitter–to back away from some of the worst doom-and-gloom hysteria. Yes, things are bad and could get worse, but is the world really coming undone over the euro zone crisis?

Earlier this week, my UF co-leader Jenn Ablan had an exclusive interview with Michael Steinhardt, one of the people who helped make hedge funds famous, and he basically said there was too much hysteria over Europe. And I think he’s onto something.

So on a real hot weekend, maybe it’s time for everyone to chillax–about the euro zone, health care, etc. Sound advice for all of us–even me.
