Can you guys listen to music/headphones?
Honestly I used to do very monotonous work myself for several years. Just keep in mind you won't be doing the same thing forever, that's the case with a lot of entry-level jobs like that. Now i've got so many things to do and have so many hats sometimes I wish I could go back to working and not thinking about it for a day
I used to internet in short periods where I was waiting for something to happen (test finish, etc) so it didn't really impact my work. FWIW i'm at work right now myself... but I know i'll get all my work done today so who cares if i'm on here for 30 minutes or whatever. My boss doesn't care as long as the work gets done, not sure what the environment is there.
As far as getting bored with the work I just used to play games to change the process to make it better/faster so it was at least somewhat different, but i'm not sure if you can do that.
