It's called getting older. I used to hate wake up, shower, goto work, home, tea telly then bed but recently I've took a different veiw on it I suppose. I'm working like hell now to cement myself hopefully an easier life later on I guess. From what I gather you enjoy your work, so stick at it,knuckle down and get yourself somewhere. I'm not saying don't have a social life, I start work at 7.30 till I'm done then I'll go to the pub with the missus and mates or something but you've gotta remember what gives you the money to go out and stuff.
It's a pretty depressed way of looking at it, working to live but it gets easier I think. Especially if your in a job you enjoy.
