It's important to take a step back every once in a while and take a look at the big picture. Why are you doing what you're doing? Is it because you enjoy it? If so, are you still enjoying it? If you can't answer that question, then it may be time to reassess your life goals.
In my case, I'd written myself into a rut. I was doing the same things every week, writing in the same two places all the time and I wasn't really enjoying it. Don't get me wrong, I DO enjoy writing. I'm passionate about the words I write. Writing is a big part of who I am today. But I stopped experiencing new things and became almost mechanical, closing myself off to the world when I write. As a direct result, I wasn't allowing myself to be inspired.
Standing in Roath Park, it's hard to believe that you're in the city. Cardiff has lush greenery to rival any countryside view, but step outside of these bubbles of tranquillity and you'll find the concrete jungle you'd expect from any city. It seems to have the best of both worlds.
That, my friends, is about as much as we can hope for. Because once we lose inspiration, we become lost ourselves. So, seek it often and everywhere. And know when to step away.
