Lot's of look-at-me!'s and comments about "wasting time" in this thread.
To the look-at-me's: congrats. You're doing great and we're all very proud.
To the folks concerned about wasting time: what's wrong with that? Does every moment of one's like need to be spent doing something constructive? Furthermore, how do you decide what is and isn't constructive? A few centuries ago it was agreed that reading was not merely a recreational waste of time, but actually harmful to individuals and society (look up the "Reading Mania" if you care to).
I argue that, if you don't mind being vapid, go ahead and browse your phone and argue on social media sites. If you want to be an interesting conversationalist: read, write, and quietly reflect. If you simply cannot do nothing, then knit some socks on the bus. But whatever you do, take care not to do it for the sole purpose of "not wasting time".
