What is Really, Truly Worth Your Time?

Happy Friday everyone!  In honor of the approaching weekend, I wanted to do something fun today.  Inspired by a previous Real Simple magazine article, I want to know what things in your life are really, truly worth your time.  I will be featuring your responses on a future blog post and I can't way to read them!
Here are a few simple things from the magazine that are more than worth your time:

• Calling someones supervisor to say job well done.
• Taking an affordable class or workshop that doesn't have anything to do with your career.
• People watching on public transportation.
• Putting down the box and baking a cake from scratch.
• Holding the door open for someone.
• Writing thank you notes.
• Documenting one week of your life in a journal.
• Taking a road trip and stopping at every cheesy, roadside attraction along the way.

This topic makes me think of one of my favorite (yet slightly cheesy) quotes: "Yesterday is history, tomorrow a mystery, today is a gift, that's why it's called the present."
What do you think?  What things in your life are really, truly worth your time?
