2. Stop Taking Selfies
Why do you need to take a picture of yourself at the gym? You look like an idiot and people are waiting to get on the machine that you're not using but because you're too busy taking photos of yourself not working out, as evidence for your actual workout, people are getting rather miffed off. Because if you didn't take a picture of yourself at the gym, then how will everyone know that it actually happened? This needs to stop. Especially the people who lift their clothing to reveal their midriffs... no one needs to see that.
