Things.

A newly released movie.
The smell of fresh ink on paper.
A new book.
An unopened adventure.
A pair of shoes that fits perfectly.
Getting an A on a test.
A bike ride on a cold day.
Going down the highway really fast.
Having no homework.
Giving the perfect gift.
Finishing something.
Selling something.
Doing something worthwhile.
Seeing someone's proud of you.
Getting compliments when you feel ugly.
Someone telling you you're worth something.
Realising you are single.
Knowing that you are free.
Knowing that what you did doesn't matter.
Satisfaction.
That song that defines your life.
Getting a letter.
Writing a letter.
Being missed.
Having someone concerned for you.
This is pleasure.
These are things that bring me happiness.
