1. not usual, common, or ordinary
  2. strange, uncommon, rare, odd or weird

Everybody likes to think they are unusual, special, or different, a beautiful or unique snowflake. Are we all snowflakes? If so we still have a lot of common qualities, nothing truely unusual like being a blue snowflake, or one that won't melt. The snowflake analogy fails us we have the ability to vary more greatly then crystalized water. But it is just an ability, you must embrace the opportunities to define yourself, through experience, books, etc. It is your choice to be usual or unusual.
