We all waste time doing something. I recently got out of a 2 year relationship, and when I look back at all the times I'd spent doing stuff that I didn't enjoy to make her happy, I wish I could have just played more video games. And there was a point years ago when I would play my guitar every free minute, sometimes 12+ hrs a day on weekends. My friends were all partiers, and they would say that I had no "life". The thought of getting drunk every weekend and chasing tail wasn't my idea of a good time and they didn't understand that.
Anyway, I'm not trying hijack your thread or anything. Just saying that the ideal "life" of others is just the life they want or that they'd been lead to believe they should pursue by the media and their peers.
