Downside to being a computing student:

I need my PC to study, but all my distractions are on my PC so it's really hard not to get distracted while studying.

What I did (or tried to do) to avoid being tempted to play computer games while studying was to dual-boot and have the games only in the Windows partition and the study material only in the Linux partition. That way a change of activity would require me a reboot.

@cafecortado that's smart, but it's not just games that I get distracted with. Sometimes I end up on reddit and other times I end up programming stuff that's completely unrelated to the course because I have some cool idea for some project

Play on hard mode:
Rely on discipline

Or play on easy mode and find a study partner.

Personally, I just have two separate locations.

One in the living room, where I fuck around, and the other, at the kitchen table where I work.

Having separate spaces, or even just surfaces, to distinguish activities, goes a long way toward reinforcing discipline.

It also helps if your income relies on this fact. You don't work, you don't eat.

@Wisecrack that's a very good one. Thank you :D

Be poor.
Then you can only afford shitty chuwi laptops w/ 4gB of RAM and you can only brows for RFCs because a website like Reddit is too heavy ;)
