I was playing 4-6 hours per day when I was 11-14 and 6-12 hours per day when I was 15-20. Playing video games got me into computers. Unlike your indecisive personality, I knew what I wanted to do since I was 11. Work with computers. By my estimates, I've spent over 25,000 hours playing video games.
I'm not sure what I would have done with my life if I didn't get into gaming/computers. I was a "D" student in school. College was a breeze because I got to do what I loved. I probably never would have gone to college if I didn't have my love for computers, as I was generally a failure in school.
You know all those other people who didn't "waste" their free time on the computer... Yeah, they go out to bars every night, have no savings, are divorced, and job hop. They may get out more than me, but I do not envy their life. I've only had a job with benefits for 3 years now, and my 401k is larger than most 50 year olds that I know.
At least in my case, I would not have "thanked" you.
Personally, I was the one the maintained the family computer anyway. I was the admin. If someone needed something, they came to me and I set it up for them.
