Nowadays, I don't really bother since I go to school, study a lot, work and work out.
When I was 18-20 years old, I somewhat mastered Codemasters Grid. At some point, I was ranked 83rd in the world which is not that bad considering there were over 500 000 accounts. Do I regret the 10 hours a day I invested racing in that game? Not at all! Would I do it again today? Nope!
I see that part of my life as something I'm proud of but would not do again because I don't want to play games anymore when I don't feel like it. I now see video games as a way to enjoy some free time and I don't want to see them as a job.
Other than that, I played a lot of Midnight Club 2 and I guess I'm not too bad at it, but nowhere near the level I attained with Grid.
