Contenders for the Official Slogan of My Childhood

We all remember the things our parents said to us so often that they became part of the soundtrack of our youth, right? Well, these are the ones I always consider making into t-shirts to give my sister.
  1. Life is not fair.
  2. There's always room for improvement.
  3. Think before you speak.
  4. If you were really sorry you wouldn't have done it.
  5. There is no try.
