Its not bad at all if you do something else throughout the day.
Wake up early and workout before you get to work, and eat a good breakfast. Not that McDonalds shyt.
Get through your work, and bring a book, or work on a book when you're free during work.
Ignore the moaning and groaning of your fellow workers, they'll have you feeling a different way than you actually do.
After work, do something besides going out for a drink, or sitting on the couch and drinking a beer.
Hobbies and physical activity motherfukker. Writing and playing music, reading books, video games if that's your think, drawing, painting, yoga, meditation, programming, movies, cooking new creations, find friends and do something, pickup basketball, football, soccer, concerts.
Its not at all bad, work on a side business using the stable money you're making now. There are thousands of ways to do this, and if you're living your life right, those 7-8 hours won't be bad at all.
