Several things.
The first thing is my inability to keep promises to myself. What do I mean by this? I'll give an example.
There was a hugeass history test a few days ago, which we were supposed to have before vacation, but the professor's father died, so it was postponed. I wanted to study during vacation, but just didn't have the will, despite promising myself that I am going to do just that. Vacation finished. Had 2 more days until the test. Promised myself again I was gonna study my ass off, no, didn't happen. Last day, the morning before test-day (I had school in the afternoon this week). My alarm wakes me up at 8 AM, I promise myself that I was going to get up, nope. I turned off the alarm and woke up at 10 AM. 4 more hours until school. Did I study? No.
"Bleh, I'll sit at the PC for an hour, and then I have another 3 hours, yay!"
one hour later...
"30 minutes more, 2 and a half hours is plenty."
30 minutes later..
"2 hours is enough."
1 hour later...
"Meh, 30 minutes is all I need, I studied before vacation, I just need to revize."
30 minutes later..
"Right! Let's get to work!"
You can forsee what happened next. I didn't know **** on the test and now I'm prly gonna get a 1, equivalent to an F in the US. This happens to me once in a while, and sometimes consistently. I HATE IT!! It's happening right now, I'm supposed to study chemistry, but I'm still replying to this. Sad...
Second thing, World of Warcraft.
Third thing, I love to eat FAST AND A LOT, which ends up in heartburn several hours later.
