23, full time student, part time developer. Worked full time over the summer, still found time to cater for a friend's wedding over the summer, everything cooked from scratch. Start work at 9am, finish between 10pm and 2am, 5 days a week.
My dad was a builder, packed it in after an injury, went into computing. Much like yourself, his aim was that I didn't have to do that sort of work myself.
I have slow patches, but I get ill easily, and I've been ill for 8 weeks after putting in the 70-80hr weeks I have been. I have barely played a computer game for 6 months.
Spent about a year out of full time work since i was 18 (my 2nd year), worked for my dad since I was a kid. Was still developing and labouring on the side during my 2nd year.
I don't get on with my family - if everything falls apart I simply don't have anywhere to go. I have to work hard because noone else is going to do it for me.
