If you do things differently from other people, you will get noticed.
What a simple statement but how it relates to so many things in life.
If you come to class on days when other students are skipping, the lecturer will remember your face.
If you go to work early and others are late, your boss will appreciate your effort.
If you listen attentively in a boring speech and discuss with the speaker about his/her ideas afterwards, it will make a difference.
You don't have to be the most interesting or unique individual, you just have to be smart about things.
