Feelings are a consequence of the events of your day. Working quietly beneath the radar of rational thought, feelings can last a moment or a lifetime. Feelings represent your honest response to the events at hand. They are a gateway to understanding your character more deeply - appreciating what really matters to you and what makes you feel alive.
Here are a diversity of perspectives from the movies about feelings.

"People are easiest to read when they're hurting."
"It is more difficult to pretend that you do have feelings when you don't than to pretend you don't have feelings when you do."
