"Realize" is a song by American singer-songwriter Colbie Caillat, taken from her debut album, Coco (2007).

Scenes also show Colbie singing the song in the forest, and with her guitar in the sunlight during sunset.

[citation needed] As explained on her 2008 summer tour with John Mayer, there is a story behind this song.

[citation needed] Caillat, Jason Reeves, and his roommate were a close group of three friends.

Colbie was unaware that Jason's roommate had a huge crush on her, and when she found out about this later, she decided to base her song on this.
