Career: working with computer hardwares, maybe as an hw engineer, system/network builder, anything like that. If i would have this job, then i wont need to work a day, i would do my hobby in big for money. There is good money in there.
Get cars, a high end computer (seriously because of my job ), a nice house.
Get married with someone who i love.
Children? no, i am really concerned about that i would be the shittiest dad in the world. that is for sure.
For retirement? usuals, grow a beard, get some tattoo, and tell my grandchildren (if there will be any) that i was a hells angel rider, a big badass. aww yea, sweet dreams.
