I, too, love long approaches. For me it's a simple matter of excitement versus anxiety.
A shot that I should be able to execute gives me anxiety.

I relish long approaches because they often offer somewhat warmer invitations for shot-shaping. Shorter approaches seem to bark cold demands.
With shorter full-swing approaches there is often a clear ideal course of action. i.e - No wind, 135 yards, slightly elevated green with a shoulder bunker left. My play is a high, hard 9 5 paces right of the pin. Now EXECUTE!!!
But if I'm standing 208 out, I have to think about ALL of the hazards around the green. The wind can be more of an ally - or enemy. The flow of the land makes suggestions you tend to ignore with a short iron in your hands. Suddenly as many as 3 different clubs are viable options.
Key to it all may just be that, as suggested by JMEvensky, the definition of success is expanded. Your gut doesn't ache if you end up on the wrong tier of the green, as it does with a wedge approach. Instead, you celebrate being on the green at all.
But more than anything, long approach shots make better fish stories in the postround grill.
