I felt the same way when I was in my early 20s, had recently graduated from college, was single and had few friends. My idea of a good Saturday was one in which I sat at a coffee shop by myself and continued working.

A decade later, my perspective has widened and my priorities have shifted. I still derive a lot of pleasure from work (even though I wouldn't describe it as "molding reality"), but I also realize that work is ultimately a means to an end, which is to spend time with my friends and loved ones and/or develop my hobbies.
