Finding beauty in life's simplest pleasures is what makes me happiest. Getting caught up in the complexities of our daily lives, after all, is what keeps us from truly enjoying life. I find great pleasure in finding ways for the things we interact with on a daily basis to be more efficient. Which leads to the best feeling in the world: taking something that would otherwise seem drab or commonplace and being able to turn it into something useful, or better, aesthetically pleasing to one's intrigue. Whether it's photography, music, engineering, or love, life is full of opportunities for the artistic expression of joy and happiness.
Ultimately, I just enjoy capturing the simplest things in life and admiring how beautiful the world can be if you just slow down long enough to appreciate it!
