Nice post. I just find some of it funny....

Walking fast - usually done by people who are late or always late for something.

Sitting in the front row - i dont do this, i am not sure if the speaker has halitosis and I certainly will not like having his saliva on my face!

Speaking up - have to be done in moderation. They might say you talk way too much.

Posture - You can't always just sit upright when you're head is full of things to do.
Have you ever tried figuring out a solution with your all strain on your posture?

Compliment others - extra care when doing this, you might be called an ar*e-licker.

Lastly,

just be yourself and others will see through that...

Cheers!
