Lack of (career) ambition. Because of a workaholic dad I sworn to myself to always choose an easy worklife. Take the easy path. Currently in a family with kids and a nice job, but I lack the motivation to really make a career. Sure it's a fun (programming) job with a lot of freedom. But I only do what is necessary, nothing more. Money is not an issue or driver for me. People may see me as lazy. Will I regret this?

Also, is playing videogames in your thirties considered childish? I sometimes get the impression that people do. Not sure how to respond to that.
