"Ramps are wet from rain a couple days ago..."

"Racks on the car need to be replaced..."
"Local trails/spots/climbs are getting boring..."
For some, it's the event before the event (of riding your bike) that gets in the way of riding your bike. Of course, there are true legitimate reasons not to ride, like an injury and a true mechanical issue - but for the most part, you can "ride" without all the foreplay.
People who know me, know I hate driving to ride. To me, it's the most ironic, un-bike-like thing you can do. Of course, there are events, spots and trails to travel to enjoy (I get out to Santa Cruz every few weeks), but 95% of my riding is stepping outside my front door - how it was when I was a kid.
Us "hardcores" sure can take a lesson from the recreational riders in this regard. Try refraining from the race kit, the Hydropack, the lycra, the special shoes, safety armor, the loading of bikes... and step out your front door: just you and your bike and start pedaling. Just pedal and let the ride become itself - organically. The process of "not having a process" can be extremely therapeutic.
