I don't have social media for this very reason. I know I'd become too addicted and would not be able to do anything else. It'd suck me in and I would find myself addicted and feeling the need to log in every 5 minutes to check for updates. I have grades to get, and the highest possible ones at that. I am often tempted to join as I know that I could communicate easier with some people, but I always refrain. Once you're in you cannot escape. It's like a drug, you become addicted and cannot stop, you promise yourself you'll go off in '5 minutes', that turns into 10, trickles to 15, then half an hour, then an hour, and before you know it you've wasted hours of time on that without doing any revision or important stuff. This site is possibly the only exception, I find it to not be addictive somehow. It's a lovely site but I'm not addicted to it thankfully.
