I went through a similar period when I was first certified here in San Diego. I did a number of dives at the same place where I did my OW training. As the novelty of the whole scuba experience wore off, I became bored with the dive site. I considered becoming strictly a vacation diver. Thankfully, I continued to dive locally because my friends made the entire experience so much fun...I just wasn't so thrilled with the UW part (which lasted a few months). Yeah, I'll admit that sounds a little strange.
Fast forward about a decade. I'm still diving the same spot with the same buddies. The difference is that I'm constantly amazed by how much life there is. The "big" stuff isn't always there, but there's always small stuff...really tiny stuff...stuff so small and camouflaged that it's incredible when you finally notice it. It's fun to see the UW landscape change over the weeks, months, and years. I'm no longer bored with the site. I feel really lucky to be able to dive it.
